Preguntes més freqüents

El navegador Tor evita que la gent conegui els llocs web que visiteu. Algunes entitats, com ara el vostre proveïdor de serveis d’Internet (ISP), poden veure que esteu utilitzant Tor, però no saben on aneu quan ho feu.

El navegador Tor segurament pot ajudar els usuaris a accedir al vostre lloc web des de llocs on està blocat. Normalment, només cal baixar el Navegador Tor i utilitzar-lo per a navegar per la pàgina blocada permetrà accedir-la. En llocs on hi ha una gran censura, tenim disponibles diverses opcions d’elusió contra la censura, incloent transports connectables.

Desaconsellem encaridament que instal·leu nous complements al navegador Tor, ja que poden comprometre la vostra privadesa i seguretat.

Installing new add-ons may affect Tor Browser in unforeseen ways and potentially make your Tor Browser fingerprint unique. If your copy of Tor Browser has a unique fingerprint, your browsing activities can be deanonymized and tracked even though you are using Tor Browser.

Basically, each browser's settings and features create what is called a "browser fingerprint". Most browsers inadvertently create a unique fingerprint for each user which can be tracked across the internet. Tor Browser is specifically engineered to have a nearly identical (we're not perfect!) fingerprint across it's users. This means each Tor Browser user looks like every other Tor Browser user, making it difficult to track any individual user.

There's also a good chance a new add-on will increase the attack surface of Tor Browser. This may allow sensitive data to be leaked or allow an attacker to infect Tor Browser. The add-on itself could even be maliciously designed to spy on you.

El navegador Tor ja ve instal·lat amb dos complements: HTTPS Everywhere i NoScript, i afegir-hi qualsevol altra cosa podria fer perdre l'anonimat.

Want to learn more about browser fingerprinting? Here's an article on The Tor Blog all about it!

Tor Browser is currently available on Windows, Linux and macOS.

There is a version of Tor Browser for Android and The Guardian Project also provides the app Orbot to route other apps on your Android device over the Tor network.

There is no official version of Tor for iOS yet, though we recommend Onion Browser.

En termes generals, no recomanem utilitzar una VPN amb Tor llevat que sigueu un usuari avançat que sàpiga com configurar-los d'una manera que no comprometi la vostra privadesa.

About Tor

The name "Tor" can refer to several different components.

Tor is a program you can run on your computer that helps keep you safe on the Internet. It protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. This set of volunteer relays is called the Tor network.

The way most people use Tor is with Tor Browser, which is a version of Firefox that fixes many privacy issues. You can read more about Tor on our about page.

The Tor Project is a non-profit (charity) organization that maintains and develops the Tor software.

Because Tor is the onion routing network. When we were starting the new next-generation design and implementation of onion routing in 2001-2002, we would tell people we were working on onion routing, and they would say "Neat. Which one?" Even if onion routing has become a standard household term, Tor was born out of the actual onion routing project run by the Naval Research Lab.

(It's also got a fine translation from German and Turkish.)

Note: even though it originally came from an acronym, Tor is not spelled "TOR". Only the first letter is capitalized. In fact, we can usually spot people who haven't read any of our website (and have instead learned everything they know about Tor from news articles) by the fact that they spell it wrong.

A typical proxy provider sets up a server somewhere on the Internet and allows you to use it to relay your traffic. This creates a simple, easy to maintain architecture. The users all enter and leave through the same server. The provider may charge for use of the proxy, or fund their costs through advertisements on the server. In the simplest configuration, you don't have to install anything. You just have to point your browser at their proxy server. Simple proxy providers are fine solutions if you do not want protections for your privacy and anonymity online and you trust the provider to not do bad things. Some simple proxy providers use SSL to secure your connection to them, which protects you against local eavesdroppers, such as those at a cafe with free wifi Internet.

Simple proxy providers also create a single point of failure. The provider knows both who you are and what you browse on the Internet. They can see your traffic as it passes through their server. In some cases, they can even see inside your encrypted traffic as they relay it to your banking site or to ecommerce stores. You have to trust the provider isn't watching your traffic, injecting their own advertisements into your traffic stream, or recording your personal details.

Tor passes your traffic through at least 3 different servers before sending it on to the destination. Because there's a separate layer of encryption for each of the three relays, somebody watching your Internet connection can't modify, or read, what you are sending into the Tor network. Your traffic is encrypted between the Tor client (on your computer) and where it pops out somewhere else in the world.

Doesn't the first server see who I am?

Possibly. A bad first of three servers can see encrypted Tor traffic coming from your computer. It still doesn't know who you are and what you are doing over Tor. It merely sees "This IP address is using Tor". Tor is not illegal anywhere in the world, so using Tor by itself is fine. You are still protected from this node figuring out both who you are and where you are going on the Internet.

Can't the third server see my traffic?

Possibly. A bad third of three servers can see the traffic you sent into Tor. It won't know who sent this traffic. If you're using encryption (like HTTPS), it will only know the destination. See this visualization of Tor and HTTPS to understand how Tor and HTTPS interact.

There is absolutely no backdoor in Tor.

We know some smart lawyers who say that it's unlikely that anybody will try to make us add one in our jurisdiction (U.S.). If they do ask us, we will fight them, and (the lawyers say) probably win.

We will never put a backdoor in Tor. We think that putting a backdoor in Tor would be tremendously irresponsible to our users, and a bad precedent for security software in general. If we ever put a deliberate backdoor in our security software, it would ruin our professional reputations. Nobody would trust our software ever again - for excellent reason!

But that said, there are still plenty of subtle attacks people might try. Somebody might impersonate us, or break into our computers, or something like that. Tor is open source, and you should always check the source (or at least the diffs since the last release) for suspicious things. If we (or the distributors) don't give you source, that's a sure sign something funny might be going on. You should also check the PGP signatures on the releases, to make sure nobody messed with the distribution sites.

Also, there might be accidental bugs in Tor that could affect your anonymity. We periodically find and fix anonymity-related bugs, so make sure you keep your Tor versions up-to-date.

No, it doesn't. You need to use a separate program that understands your application and protocol and knows how to clean or "scrub" the data it sends. Tor Browser tries to keep application-level data, like the user-agent string, uniform for all users. Tor Browser can't do anything about text that you type into forms, though.

There are plenty of other programs you can use with Tor, but we haven't researched the application-level anonymity issues on all of them well enough to be able to recommend a safe configuration. Our wiki has a community-maintained list of instructions for Torifying specific applications. Please add to these lists and help us keep them accurate!

Most people use Tor Browser, which includes everything you need to browse the web safely using Tor. Using Tor with other browsers is dangerous and not recommended.

Yes.

The Tor software is free software. This means we give you the rights to redistribute the Tor software, either modified or unmodified, either for a fee or gratis. You don't have to ask us for specific permission.

However, if you want to redistribute the Tor software you must follow our LICENSE. Essentially this means that you need to include our LICENSE file along with whatever part of the Tor software you're distributing.

Most people who ask us this question don't want to distribute just the Tor software, though. They want to distribute the Tor Browser. This includes Firefox Extended Support Release, and the NoScript and HTTPS-Everywhere extensions. You will need to follow the license for those programs as well. Both of those Firefox extensions are distributed under the GNU General Public License, while Firefox ESR is released under the Mozilla Public License. The simplest way to obey their licenses is to include the source code for these programs everywhere you include the bundles themselves.

Also, you should make sure not to confuse your readers about what Tor is, who makes it, and what properties it provides (and doesn't provide). See our trademark FAQ for details.

Navegador Tor

La signatura digital és un procés que assegura que un paquet determinat ha estat generat pels seus desenvolupadors i no ha estat alterat. Below we explain why it is important and how to verify that the Tor program you download is the one we have created and has not been modified by some attacker.

Each file on our download page is accompanied by a file with the same name as the package and the extension ".asc". These .asc files are OpenPGP signatures. They allow you to verify the file you've downloaded is exactly the one that we intended you to get. For example, torbrowser-install-win64-8.5.5_en-US.exe is accompanied by torbrowser-install-win64-8.5.5_en-US.exe.asc.

We now show how you can verify the downloaded file's digital signature on different operating systems. Please notice that a signature is dated the moment the package has been signed. Therefore every time a new file is uploaded a new signature is generated with a different date. As long as you have verified the signature you should not worry that the reported date may vary.

Installing GnuPG

First of all you need to have GnuPG installed before you can verify signatures.

For Windows users:

If you run Windows, download Gpg4win and run its installer.

In order to verify the signature you will need to type a few commands in windows command-line, cmd.exe.

Per a usuaris macOS:

If you are using macOS, you can install GPGTools.

In order to verify the signature you will need to type a few commands in the Terminal (under "Applications").

For GNU/Linux users:

If you are using GNU/Linux, then you probably already have GnuPG in your system, as most GNU/Linux distributions come with it preinstalled.

In order to verify the signature you will need to type a few commands in a terminal window. How to do this will vary depending on your distribution.

Fetching the Tor Developers key

The Tor Browser team signs Tor Browser releases. Import the Tor Browser Developers signing key (0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290):

gpg --auto-key-locate nodefault,wkd --locate-keys torbrowser@torproject.org

This should show you something like:

gpg: key 4E2C6E8793298290: public key "Tor Browser Developers (signing key) <torbrowser@torproject.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1
pub   rsa4096 2014-12-15 [C] [expires: 2020-08-24]
      EF6E286DDA85EA2A4BA7DE684E2C6E8793298290
uid           [ unknown] Tor Browser Developers (signing key) <torbrowser@torproject.org>
sub   rsa4096 2018-05-26 [S] [expires: 2020-09-12]

After importing the key, you can save it to a file (identifying it by fingerprint here):

gpg --output ./tor.keyring --export 0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290

Verifying the signature

To verify the signature of the package you downloaded, you will need to download the corresponding ".asc" signature file as well as the installer file itself, and verify it with a command that asks GnuPG to verify the file that you downloaded.

The examples below assume that you downloaded these two files to your "Downloads" folder.

The result of the command should produce something like this:

gpgv: Signature made 07/08/19 04:03:49 Pacific Daylight Time
gpgv:                using RSA key EB774491D9FF06E2
gpgv: Good signature from "Tor Browser Developers (signing key) <torbrowser@torproject.org>"

For Windows users:

gpgv --keyring .\tor.keyring Downloads\torbrowser-install-win64-8.5.5_en-US.exe.asc Downloads\torbrowser-install-win64-8.5.5_en-US.exe

Per a usuaris macOS:

gpgv --keyring ./tor.keyring ~/Downloads/TorBrowser-8.5.5-osx64_en-US.dmg{.asc,}

For GNU/Linux users (change 64 to 32 if you have the 32-bit package):

gpgv --keyring ./tor.keyring ~/Downloads/tor-browser-linux64-8.5.5_en-US.tar.xz{.asc,}

Cada vegada que publiquem una nova versió estable del navegador Tor, escrivim una publicació de blog que detalla les seves noves funcions i problemes coneguts. If you started having issues with your Tor Browser after an update, check out blog.torproject.org for a post on the most recent stable Tor Browser to see if your issue is listed. Si el vostre problema no apareix, envieu un informe d'error sobre el que estigueu experimentant.

La majoria de la protecció antivirus o de programari maliciós permet a l'usuari "llistes blanques" certs processos que d'una altra forma serien blocats. Obriu l'antivirus o la protecció de programari maliciós i cerqueu a les opcions «Llista blanca» o alguna cosa semblant. A continuació, s'exclouen els següents processos:

  • Per Windows
    • firefox.exe
    • tor.exe
    • obfs4proxy.exe (si utilitzes ponts)
  • Per a macOS
    • Navegador Tor
    • tor.real
    • obfs4proxy (si utilitzeu ponts)

Finalment, reinicieu el navegador Tor. Això solucionarà els problemes que estigueu experimentant. Tingueu en compte que alguns clients antivirus, com Kaspersky, també poden blocar Tor al nivell de tallafocs.

El fitxer que heu baixat i executat us demana un lloc per la destinació. Si no recordeu quina era aquesta destinació, és probable que sigui la vostra carpeta de baixades o l'escriptori.

The default setting in the Windows installer also creates a shortcut for you on your Desktop, though be aware that you may have accidentally deselected the option to create a shortcut.

Si no podeu trobar-lo en cap d'aquestes carpetes, torneu a baixar-lo i busqueu l'indicador que us demanarà que trieu un directori per baixar-lo. Trieu una ubicació del directori que us recordeu fàcilment i, un cop finalitzada la baixada, heu de veure una carpeta del navegador Tor allà.

Flash is disabled in Tor Browser, and we recommend you to not enable it. No creiem que Flash sigui segur d'utilitzar en qualsevol navegador: és una peça de programari molt insegura que pot comprometre la vostra privadesa fàcilment o oferir-vos programari maliciós. Afortunadament, la majoria de llocs web, dispositius i altres navegadors s'estan allunyant de l'ús de Flash.

Només el trànsit del navegador Tor s'enviarà a la xarxa Tor. Qualsevol altra aplicació del vostre sistema (inclosos altres navegadors) no tindrà les seves connexions encaminades a la xarxa Tor i no estarà protegida. Han de configurar-se per separat per utilitzar Tor. Si heu d'assegurar-vos que tot el trànsit passarà per la xarxa Tor, feu un cop d'ull al sistema operatiu Tails Live que podreu iniciar a gairebé qualsevol ordinador des d'un llapis USB o un DVD.

Malauradament, encara no tenim una versió del navegador Tor per al Chrome OS. You could run Tor Browser for Android on Chrome OS. Note that by using Tor Mobile on Chrome OS, you will view the mobile (not desktop) versions of websites. However, because we have not audited the app in Chrome OS, we don't know if all the privacy features of Tor Browser for Android will work well.

Modificar la manera en què Tor crea els seus circuits és molt poc recomanable Obteniu la millor seguretat que Tor pot proporcionar quan deixeu la selecció de ruta a Tor; reemplaçar els nodes d'entrada i sortida pot comprometre l'anonimat. Si el resultat que voleu és simplement poder accedir a recursos que només estan disponibles en un sol país, és possible que vulgueu considerar l'ús d'una VPN en lloc d'utilitzar Tor. Tingueu en compte que les VPN no tenen les mateixes propietats de privadesa que Tor, però ajudaran a resoldre alguns problemes de restricció de geolocalització.

Si executeu el navegador Tor i un altre navegador alhora, no afectarà el rendiment o les propietats de privadesa de Tor. Tanmateix, tingueu en compte que el vostre altre navegador no manté la privadesa de la vostra activitat i us pot oblidar i utilitzar accidentalment aquest navegador no privat per fer alguna cosa que voleu fer al navegador Tor.

Ho sentim, però actualment no hi ha suport oficial per executar el navegador Tor a *BSD. Hi ha alguna cosa anomenat projecte TorBSD, però el seu navegador Tor no és està oficialment suportat.

Pot ser que estigueu en una xarxa censurada i, per tant, podeu provar utilitzar ponts. Alguns ponts es creen al navegador Tor, i podeu utilitzar aquests ponts triant "configurar" (seguint les indicacions) a la finestra Tor Launcher que apareix quan obriu el navegador Tor per primera vegada. If you need other bridges, you can get them at our Bridges website. For more information about bridges, see the Tor Browser manual.

Aquest és un comportament normal a Tor El primer repetidor del circuit es diu "guarda d'entrada" o "guarda". Es tracta d'un repetidor ràpid i estable que segueix sent el primer del vostre circuit durant 2-3 mesos per protegir-se contra un atac conegut que trenca l'anonimat. La resta del circuit canvia amb cada nou lloc web que visiteu, i tots junts aquests repetidors proporcionen les proteccions completes de la privacitat de Tor. Per obtenir més informació sobre com funcionen els repetidors de guarda, consulteu aquesta publicació i publicació de blog sobre guàrdies d'entrada.

Un dels problemes més comuns que causa errors de connexió al navegador Tor és un rellotge del sistema incorrecte. Assegureu-vos que el rellotge del sistema i el fus horari estiguin configurats amb precisió. If this doesn't fix the problem, see the Troubleshooting page on the Tor Browser manual.

Feu clic al botó anomenat "Copia registre Tor al portapapers" que apareix a la finestra de diàleg quan el navegador Tor es connecta per primera vegada a la xarxa. Si el navegador Tor ja està obert, feu clic a la icona de Tor (la ceba petita verda a la part superior esquerra de la pantalla), a continuació, "Obre la configuració de la xarxa" i, a continuació, "Copia el registre de Tor al portapapers". Un cop copiat el registre, podreu enganxar-lo en un editor de text o un client de correu electrònic.

L'ús del navegador Tor a vegades pot ser més lent que altres navegadors. La xarxa Tor té més d'un milió d'usuaris diaris, i poc més de 6000 repetidors per recórrer tot el seu trànsit, i la càrrega de cada servidor pot provocar sw vegades latència. You can help improve the speed of the network by running your own relay, or encouraging others to do so. Dit això, Tor és molt més ràpid del que era, i és possible que no detecteu canvis en la velocitat d'altres navegadors.

DuckDuckGo és el motor de cerca predeterminat del navegador Tor. DuckDuckGo no fa el seguiment dels seus usuaris ni emmagatzema dades sobre les cerques dels usuaris. Més informació sobre la política de privadesa de DuckDuckGo.

Consulteu el portal d'assistència DuckDuckGo. Si creieu que aquest és un problema del navegador Tor, informeu-lo al nostre seguidor d'errors.

Consulteu les PMF de NoScript. Si creieu que aquest és un problema del navegador Tor, informeu-lo al nostre seguidor d'errors.

Siusplau mira laHTTPS Everywhere FAQ. Si creieu que aquest és un problema del navegador Tor, informeu-lo al nostre seguidor d'errors.

EL Navegador Tor té dues maneres de canviar el circuit del repetidor: "Nova identitat" i "Nou circuit Tor per a aquest lloc".

Ambdues opcions es troben al Menú, però també podeu accedir a l'opció Nou Circuit dins del menú d'informació del lloc, a la barra d'URL.

Nova identitat

Aquesta opció és útil si voleu evitar que la vostra activitat posterior del navegador sigui vinculada al que hagueu fet abans.

Si ho seleccioneu, tanqueu totes les pestanyes i finestres, esborreu tota la informació privada, com ara les galetes i l'historial de navegació, i utilitzeu els nous circuits Tor per a totes les connexions.

El navegador Tor us avisarà que tota activitat i baixades s'aturaran, així que teniu això en compte abans de fer clic a «Identitat nova».

Tor Browser Menu

Nou Circuit Tor per a aquest lloc

Aquesta opció és útil si el repetidor de sortida que utilitzeu no pot connectar-se al lloc web que necessiteu o no s'ha carregat correctament. Si ho seleccioneu, es tornarà a carregar la pestanya o la finestra actualment activa en un nou circuit Tor.

Altres pestanyes obertes i finestres del mateix lloc web també usaran el nou circuit una vegada que es tornin a carregar.

Aquesta opció no elimina cap informació privada o desenllaça la vostra activitat, ni afecta les vostres connexions actuals a altres llocs web.

New Circuit for this Site

El navegador Tor evita que la gent conegui els llocs web que visiteu. Algunes entitats, com ara el vostre proveïdor de serveis d’Internet (ISP), poden veure que esteu utilitzant Tor, però no saben on aneu quan ho feu.

El navegador Tor sovint fa que la vostra connexió aparegui com si provingués d'una part completament diferent del món. Alguns llocs web, com ara bancs o proveïdors de correu electrònic, poden interpretar-ho com a signe que el vostre compte s'ha vist compromès i us poden blocar.

L'única manera de resoldre això és seguir el procediment recomanat del lloc per a la recuperació del compte o posar-se en contacte amb els operadors i explicar la situació.

És possible que pugueu evitar aquest escenari si el vostre proveïdor ofereix l'autenticació de doble factor, que és una opció de seguretat molt millor que la reputació basada en IP. Poseu-vos en contacte amb el vostre proveïdor i pregunteu-los si proporcionen 2FA. (autenticació de doble factor)

Tor Browser is currently available on Windows, Linux and macOS.

There is a version of Tor Browser for Android and The Guardian Project also provides the app Orbot to route other apps on your Android device over the Tor network.

There is no official version of Tor for iOS yet, though we recommend Onion Browser.

Actualment, no hi ha cap mètode compatible per configurar el navegador Tor com a navegador predeterminat. El navegador Tor treballa fort per aïllar-se de la resta del sistema i els passos per fer-ho navegador predeterminat no va en aquesta linea. Això vol dir que de vegades es carregarà un lloc al navegador Tor, i de vegades es carregarà en un altre navegador, aquest tipus de comportament pot ser perillós i trencar l'anonimat.

Executar el navegador Tor no us fa actuar com un repetidor a la xarxa. Això significa que l'ordinador no s'utilitzarà per encaminar el trànsit per a tercers. Si voleu convertir-vos en un repetidor, consulteu la nostra Guia de repetidors de Tor.

Configurem NoScript per permetre JavaScript de manera predeterminada al navegador Tor perquè molts llocs web no funcionen amb JavaScript desactivat. La majoria dels usuaris renunciarien completament a Tor si desactivem JavaScript de manera predeterminada perquè causaria molts problemes per a ells. En definitiva, volem que el navegador de Tor sigui el més segur possible, a més de fer-lo servir per a la majoria de les persones, de moment, això vol dir que JavaScript està habilitat per defecte.

Per als usuaris que vulguin deshabilitar JavaScript en tots els llocs HTTP de forma predeterminada, us recomanem que canvieu el control lliscant de seguretat del navegador Tor (al menú Ceba de navegador Tor a "Configuració de seguretat"). The standard level allows JavaScript, but the safer and safest levels both block JavaScript on HTTP sites.

Malauradament, alguns llocs web envien CAPTCHAs als usuaris de Tor, i no podem eliminar CAPTCHAs dels llocs web. El millor que es pot fer en aquests casos és posar-se en contacte amb els propietaris del lloc web i informar-los que els seus CAPTCHAs estan impedint que els usuaris, com vostè mateix, utilitzin els seus serveis.

We do not recommend running multiple instances of Tor Browser, and doing so may not work as anticipated on many platforms.

We want everyone to be able to enjoy Tor Browser in their own language. Tor Browser is now available in 25 different languages, and we are working to add more. Want to help us translate? See here

You can also help us testing the next languages we will release, by installing and testing Tor Browser Alpha releases.

Quan utilitzeu el navegador Tor, ningú pot veure els llocs web que visiteu. Tanmateix, el vostre proveïdor de serveis o administradors de xarxa poden veure que esteu connectant a la xarxa Tor, encara que no sabran què feu quan arribeu.

De vegades, els llocs web amb molt contingut JavaScript poden tenir problemes funcionals sobre el navegador Tor. La solució més senzilla és fer clic al "menú de la ceba" i, a continuació, feu clic al control lliscant de seguretat. Establiu la seguretat a "Estàndard".

El Navegador Tor és una versió modificada de Firefox dissenyada específicament per al seu ús amb Tor. S'ha fet un gran esforç per fer que el navegador Tor, inclòs l'ús de pegats addicionals per millorar la privadesa i la seguretat. Tot i que és tècnicament possible utilitzar Tor amb altres navegadors, podeu obrir-vos a possibles atacs o filtracions d'informació, de manera que us ho desaconsellem molt. Més informació sobre el disseny del navegador Tor.

Al navegador Tor, cada nou domini rep el seu propi circuit. En el document Disseny i la implementació del navegador Tor també expliquem el pensament darrere d'aquest disseny.

Amb la publicació del Navegador Tor 6.0.6, vam passar a DuckDuckGo com a motor de cerca principal. Des de fa un temps, Disconnect no ha tingut accés als resultats de cerca de Google que hem utilitzat al navegador Tor. Atès que Disconnect és més que un meta motor de cerca que permet als usuaris triar entre diferents proveïdors de cerca, es va desestimar oferir resultats de cerca de Bing que eren bàsicament inacceptables de qualitat.

El Navegador Tor està construït utilitzant Firefox ESR, de manera que es poden produir errors respecte a Firefox. Assegureu-vos que no hi ha cap altra instància del navegador Tor que ja s'estigui executant i que hagueu extret el navegador Tor en una ubicació que el vostre usuari tingui els permisos correctes. Si esteu executant un antivirus, consulteu La meva protecció antivirus/malware no em permet accedir al navegador Tor, és habitual que el programari antivirus o antimalware produeixi aquest tipus de problema.

Certament, podeu utilitzar un altre navegador mentre feu servir el Navegador Tor. Tanmateix, haureu de saber que les característiques de privadesa del navegador Tor no estaran presents a l'altre navegador. Aneu amb compte quan canvieu entre Tor i un navegador menys segur, ja que podeu utilitzar accidentalment l'altre navegador per a alguna cosa que voleu utilitzar amb Tor.

Malauradament, no hi ha cap manera de fer que el navegador Tor sigui el vostre navegador predeterminat.

De vegades, els llocs web bloquen els usuaris de Tor perquè no poden avaluar la diferència entre l'usuari Tor mitjà i el tràfic automatitzat. La millor manera que hem tingut per que els llocs desbloquin els usuaris de Tor és que els usuaris es posin en contacte directament amb els administradors del lloc. Alguna cosa així podria funcionar:

"Hola! He intentat accedir al vostre lloc xyz.com mentre feia servir el Navegador Tor i he descobert que no permet que els usuaris de Tor accedeixin al vostre lloc. Et convido a reconsiderar aquesta decisió; Tor és utilitzat per persones de tot el món per protegir la seva intimitat i lluitar contra la censura. Blocar els usuaris de Tor, probablement blocarà persones en països repressius que vulguin utilitzar una internet lliure, periodistes i investigadors que volen protegir-se de ser descoberts, denunciants, activistes i persones habituals que volen optar per un seguiment invasiu de tercers. Si us plau, prengui una posició forta a favor de la privadesa digital i la llibertat d'internet i permeti als usuaris de Tor accedir a xyz.com.Gràcies"

En el cas dels bancs i altres llocs web sensibles, també és habitual veure blocatge basat en la geografia (si un banc sap que en general accedeix als seus serveis d'un país i, de sobte, es connecta d'un repetidor de sortida a l'altre costat del món, el vostre compte pot estar blocat o suspès).

Si no podeu connectar-vos a un servei de onion, consulteu No puc accedir a X.onion!

El navegador Tor segurament pot ajudar els usuaris a accedir al vostre lloc web des de llocs on està blocat. Normalment, només cal baixar el Navegador Tor i utilitzar-lo per a navegar per la pàgina blocada permetrà accedir-la. En llocs on hi ha una gran censura, tenim disponibles diverses opcions d’elusió contra la censura, incloent transports connectables.

Per a obtenir més informació, consulteu el Manual d’usuari navegador Tor en la secció de censura.

Recomanem encarecidament no utilitzar Tor en cap navegador que no sigui el navegador Tor. L'ús de Tor en un altre navegador pot deixar-vos vulnerable sense les proteccions de privadesa del navegador Tor.

While the names may imply otherwise, 'Incognito mode' and 'private tabs' do not make you anonymous on the Internet. They erase all the information on your machine relating to the browsing session after they are closed, but have no measures in place to hide your activity or digital fingerprint online. This means that an observer can collect your traffic just as easily as any regular browser.

Tor Browser offers all the amnesic features of private tabs while also hiding the source IP, browsing habits and details about a device that can be used to fingerprint activity across the web, allowing for a truly private browsing session that's fully obfuscated from end-to-end.

For more information regarding the limitations of Incognito mode and private tabs, see Mozilla's article on Common Myths about Private Browsing.

WARNING: Do NOT follow random advice instructing you to edit your torrc! Doing so can allow an attacker to compromise your security and anonymity through malicious configuration of your torrc.

Tor uses a text file called torrc that contains configuration instructions for how Tor should behave. The default configuration should work fine for most Tor users (hence the warning above.)

To find your Tor Browser torrc, follow the instructions for your operating system below.

On Windows or Linux:

  • The torrc is in the Tor Browser Data directory at Browser/TorBrowser/Data/Tor inside your Tor Browser directory.

On macOS:

  • The torrc is in the Tor Browser Data directory at ~/Library/Application Support/TorBrowser-Data/Tor.
  • Note the Library folder is hidden on newer versions of macOS. To navigate to this folder in Finder, select "Go to Folder..." in the "Go" menu.

Go to folder menu option.

  • Then type "~/Library/Application Support/" in the window and click Go.

Go to folder window.

Close Tor Browser before you edit your torrc, otherwise Tor Browser may erase your modifications. Some options will have no effect as Tor Browser overrides them with command line options when it starts Tor.

Have a look at the sample torrc file for hints on common configurations. For other configuration options you can use, see the Tor manual page. Remember, all lines beginning with # in torrc are treated as comments and have no effect on Tor's configuration.

Tor Messenger

No. After eleven beta releases, we discontinued support of Tor Messenger. Encara creiem en la capacitat de Tor d'utilitzar-se en una aplicació de missatgeria, però no tenim els recursos per fer-ho en aquest moment. Do you? Contact us.

Tor mòbil

Yes, there is a version of Tor Browser available specifically for Android. Installing Tor Browser for Android is all you need to run Tor on your Android device.

The Guardian Project provides the app Orbot which can be used to route other apps on your Android device over the Tor network, however only Tor Browser for Android is needed to browse the web with Tor.

The Guardian Project maintains Orbot (and other privacy applications) on Android. More info can be found on the Guardian Project's website.

Recomanem una aplicació per a iOS anomenada Navegador Onion, que es de codi obert, utilitza l'enrutament Tor, i està desenvolupada per algú que treballa de prop amb el projecte Tor. No obstant això, Apple requereix que els navegadors d'iOS utilitzin alguna cosa anomenat Webkit, que impedeix que el navegador Onion tingui les mateixes proteccions de privadesa que el navegador Tor.

Learn more about Onion Browser. Download Onion Browser from the App Store.

Actualment, no hi ha cap mètode compatible per executar Tor en Windows Phone.

While both Tor Browser for Android and Orbot are great, they serve different purposes. Tor Browser for Android is like the desktop Tor Browser, but on your mobile device. It is a one stop browser that uses the Tor network and tries to be as anonymous as possible. Orbot on the other hand is a proxy that will enable you to send the data from your other applications (E-Mail clients, instant messaging apps, etc.) through the tor network; a version of Orbot is also inside of the Tor Browser for Android, and is what enables it to connect to the Tor network. That version, however, does not enable you to send other apps outside of the Tor Browser for Android through it. Depending on how you want to use the tor network, either one or both of these could be a great option.

It will be, soon. In the meantime you can use F-Droid to download Tor Browser for Android by enabling the Guardian Project's Repository.

Learn how to add a repository to F-Droid.

Connectant a Tor

Un dels problemes més comuns que causa errors de connexió al navegador Tor és un rellotge del sistema incorrecte. Assegureu-vos que el rellotge del sistema i el fus horari estiguin configurats amb precisió. If this doesn't fix the problem, see the Troubleshooting page on the Tor Browser manual.

Si teniu problemes per connectar-vos, seleccioneu l'opció "copiar el registre de Tor al porta-retalls". A continuació, enganxeu el registre de Tor en un fitxer de text o en un altre document. Heu de veure un d'aquests errors de registre comuns (busqueu les següents línies al vostre registre de Tor):

Common log error #1: Proxy connection failure

Si veieu línies com aquestes al vostre registre de Tor, significa que no esteu connectant a un proxy SOCKS. Si es requereix un proxy SOCKS per a la configuració de la xarxa, assegureu-vos que heu introduït correctament els vostres detalls del proxy. Si no es requereix un proxy SOCKS, o no esteu segur, intenteu connectar-vos a la xarxa Tor sense un proxy SOCKS.

Common log error #2: Can’t reach guard relays

Si veieu línies com aquestes en el vostre registre Tor, significa que Tor no s'ha pogut connectar al primer node del circuit Tor. Això podria significar que estàs en una xarxa censurada.

Intenteu connectar-vos amb ponts i això hauria de solucionar el problema.

Common log error #3: Failed to complete TLS handshake

Si veieu línies com aquesta en el vostre registre Tor, significa que el vostre rellotge del sistema no és correcte. Assegureu-vos que el rellotge s'estableixi amb precisió, inclosa la zona horària correcta. Torneu a iniciar Tor.

Si no podeu arribar al servei de onion que voleu, assegureu-vos que heu introduït correctament el format de 16 caràcters o, el més nou, l'adreça de onion de 56 caràcters: fins i tot un petit error deixarà que el Navegador Tor no pugui accedir al lloc. Si encara no podeu connectar-vos al servei de onion, torneu-ho a provar més tard. És possible que hi hagi un problema de connexió temporal o que els operadors del lloc hagin permès que es desconnectés sense previ avís.

També podeu assegurar-vos que podeu accedir a altres serveis de onion connectant-vos al servei de onion de DuckDuckGo.

Censura

El navegador Tor segurament pot ajudar els usuaris a accedir al vostre lloc web des de llocs on està blocat. Normalment, només cal baixar el Navegador Tor i utilitzar-lo per a navegar per la pàgina blocada permetrà accedir-la. En llocs on hi ha una gran censura, tenim disponibles diverses opcions d’elusió contra la censura, incloent transports connectables.

Per a obtenir més informació, consulteu el Manual d’usuari navegador Tor en la secció de censura.

De vegades, els llocs web bloquen els usuaris de Tor perquè no poden avaluar la diferència entre l'usuari Tor mitjà i el tràfic automatitzat. La millor manera que hem tingut per que els llocs desbloquin els usuaris de Tor és que els usuaris es posin en contacte directament amb els administradors del lloc. Alguna cosa així podria funcionar:

"Hola! He intentat accedir al vostre lloc xyz.com mentre feia servir el Navegador Tor i he descobert que no permet que els usuaris de Tor accedeixin al vostre lloc. Et convido a reconsiderar aquesta decisió; Tor és utilitzat per persones de tot el món per protegir la seva intimitat i lluitar contra la censura. Blocar els usuaris de Tor, probablement blocarà persones en països repressius que vulguin utilitzar una internet lliure, periodistes i investigadors que volen protegir-se de ser descoberts, denunciants, activistes i persones habituals que volen optar per un seguiment invasiu de tercers. Si us plau, prengui una posició forta a favor de la privadesa digital i la llibertat d'internet i permeti als usuaris de Tor accedir a xyz.com.Gràcies"

En el cas dels bancs i altres llocs web sensibles, també és habitual veure blocatge basat en la geografia (si un banc sap que en general accedeix als seus serveis d'un país i, de sobte, es connecta d'un repetidor de sortida a l'altre costat del món, el vostre compte pot estar blocat o suspès).

Si no podeu connectar-vos a un servei de onion, consulteu No puc accedir a X.onion!

Pot ser que estigueu en una xarxa censurada i, per tant, podeu provar utilitzar ponts. Alguns ponts es creen al navegador Tor, i podeu utilitzar aquests ponts triant "configurar" (seguint les indicacions) a la finestra Tor Launcher que apareix quan obriu el navegador Tor per primera vegada. If you need other bridges, you can get them at our Bridges website. For more information about bridges, see the Tor Browser manual.

Si veieu línies com aquestes al vostre registre de Tor, significa que no esteu connectant a un proxy SOCKS. Si es requereix un proxy SOCKS per a la configuració de la xarxa, assegureu-vos que heu introduït correctament els vostres detalls del proxy. Si no es requereix un proxy SOCKS, o no esteu segur, intenteu connectar-vos a la xarxa Tor sense un proxy SOCKS.

Els repetidors pont són repetidors Tor que no figuren en el directori Tor públic. Això vol dir que els ISP o els governs que intenten blocar l'accés a la xarxa Tor no poden simplement blocar tots els ponts. Els ponts són útils per als usuaris de Tor sota règims opressors, i per a persones que volen una capa addicional de seguretat perquè estan preocupats que algú reconegui que estan connectats a una adreça IP Tor de repetidor públic.

Un pont és només un repetidor normal amb una configuració lleugerament diferent. Consulteu Com puc executar un pont per obtenir instruccions.

Diversos països, inclosos Xina i Iran, han trobat maneres de detectar i blocar connexions als ponts de Tor. Els ponts d'Obfsproxy fan addreçament afegint una altra capa d'ofuscació. La configuració d'un pont obfsproxy requereix un paquet de programari addicional i configuracions addicionals. Consulteu la nostra pàgina sobre transports connectables per obtenir més informació.

HTTPS

Tor evita que els que espien sàpiguen quins llocs visiteu. Tanmateix, la informació enviada sense xifrar a Internet mitjançant HTTP simple encara pot ser interceptada pels operadors de repetidors de sortida o qualsevol persona que observi el trànsit entre el repetidor de sortida i el lloc web de destinació. Si el lloc que esteu visitant utilitza HTTPS, el trànsit que surt del relleu de sortida es xifrarà i no serà visible per als espies.

https

Si utilitzeu HTTPS, l'URL del vostre lloc web començarà amb "https: //".

This visualization shows what information is visible to eavesdroppers with and without Tor Browser and HTTPS encryption.

The following visualization shows what information is visible to eavesdroppers with and without Tor Browser and HTTPS encryption:

  • Click the “Tor” button to see what data is visible to observers when you're using Tor. The button will turn green to indicate that Tor is on.
  • Click the “HTTPS” button to see what data is visible to observers when you're using HTTPS. The button will turn green to indicate that HTTPS is on.
  • When both buttons are green, you see the data that is visible to observers when you are using both tools.
  • When both buttons are grey, you see the data that is visible to observers when you don't use either tool.



POTENTIALLY VISIBLE DATA
Site.com
The site being visited.
user / pw
Username and password used for authentication.
data
Data being transmitted.
location
Network location of the computer used to visit the website (the public IP address).
Tor
Whether or not Tor is being used.

The short answer is: Yes, you can browse normal HTTPS Sites using Tor.

HTTPS Connections are used to secure communications over computer networks. You can read more about HTTPS here Tor Browser has the HTTPS Everywhere plugin which automatically switches thousands of sites from unencrypted "HTTP" to more private "HTTPS".

Operadors

  • No utilitzeu els paquets en els dipòsits d'Ubuntu. No s'actualitzen de forma fiable. Si els utilitzes, pots perdre estabilitat important i correccions de seguretat.
  • Determineu la vostra versió d'Ubuntu executant el següent comandament:
     $ lsb_release -c
    
  • As root, add the following lines to /etc/apt/sources.list. Replace 'version' with the version you found in the previous step:
     $ deb https://deb.torproject.org/torproject.org version main
     $ deb-src https://deb.torproject.org/torproject.org version main
    
  • Afegiu la clau gpg usada per signar els paquets executant les ordres següents:
     $ curl https://deb.torproject.org/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc | sudo apt-key add -
    
  • Executeu les ordres següents per instal·lar tor i comproveu les seves signatures:
     $ sudo apt-get update
     $ sudo apt-get install tor deb.torproject.org-keyring
    

No. Si l'aplicació de la llei s'interessa pel trànsit des del teu repetidor de sortida, és possible que els agents s'apoderin de la vostra computadora. Per aquest motiu, és millor no executar el repetidor de sortida a casa o utilitzant la vostra connexió a Internet desde casa.

al contrari, considereu executar el repetidor de sortida en una instal·lació comercial que sigui compatible amb Tor. Tingueu una adreça IP independent per al vostre repetidor de sortida i no enruteu el vostre propi trànsit a través d'ell. Per descomptat, haureu d'evitar mantenir qualsevol informació personal o sensible a l'ordinador que allotgeu el vostre repetidor de sortida.

Onion Services

Els llocs web que només són accessibles per Tor són els anomenats "onions" i finalitzen en el TLD .onion. Per exemple, la onion DuckDuckGo és https://3g2upl4pq6kufc4m.onion. Podeu accedir a aquests llocs web utilitzant el navegador Tor. Les adreces han de ser compartides amb vostè per l'amfitrió del lloc web, ja que les onions no estan indexades en els motors de cerca de la manera típica que tenen els llocs web de vanilla.

Els serveis de onion permeten que la gent navegui, però també publiqui de manera anònima, inclosa la publicació de llocs web anònims.

Els serveis de onion també es basen en el xat i l'intercanvi d'arxius sense metadades, una interacció més segura entre els periodistes i les seves fonts, com ara SecureDrop o OnionShare, actualitzacions de programari més segures i formes més segures d'arribar a llocs web populars com Facebook.

These services use the special-use top level domain (TLD) .onion (instead of .com, .net, .org, etc..) and are only accessible through the Tor network.

Quan accedeix a un lloc web que utilitza un servei de onion , el Navegador Tor mostrarà a la barra d'URL una icona d'una petita ceba verda que mostra l'estat de la vostra connexió: segur i usant un servei de onion.

Onion icon

And if you're accessing a website with HTTPS and onion service, it will show an icon of a green onion and a padlock.

Green onion with a padlock

Si no podeu arribar al servei de onion que voleu, assegureu-vos que heu introduït correctament el format de 16 caràcters o, el més nou, l'adreça de onion de 56 caràcters: fins i tot un petit error deixarà que el Navegador Tor no pugui accedir al lloc. Si encara no podeu connectar-vos al servei de onion, torneu-ho a provar més tard. És possible que hi hagi un problema de connexió temporal o que els operadors del lloc hagin permès que es desconnectés sense previ avís.

També podeu assegurar-vos que podeu accedir a altres serveis de onion connectant-vos al servei de onion de DuckDuckGo.

When browsing an Onion Service, Tor Browser displays different onion icons in the address bar indicating the security of the current webpage.

Image of a green onion A green onion means:

  • The Onion Service is served over HTTP, or HTTPS with a self-signed certificate.

Image of a green onion with a lock A green onion with a lock means:

  • The Onion Service is served over HTTPS with a CA-Issued certificate.

Image of a grey onion with a red slash A grey onion with a red slash means:

  • The Onion Service is served over HTTPS with a self-signed or CA-Issued certificate.
  • The webpage contains subresources served over HTTP.

L'equip de la comunitat ha desenvolupat aquest Glossari de termes sobre i relacionats amb Tor

A

add-on, extension, or plugin

Add-ons, extensions, and plugins are components that can be added to web browsers to give them new features. Tor Browser comes with two add-ons installed: NoScript and HTTPS Everywhere. You should not install any additional add-ons to Tor Browser because that can compromise some of its privacy features.

antivirus software

An antivirus software is used to prevent, detect and remove malicious software. Antivirus software can interfere with Tor running on your computer. You may need to consult the documentation for your antivirus software if you do not know how to allow Tor.

App

A web application (web app), is an application which the client runs in a web browser. App can also refer to software that you install on mobile operating systems.

Atlas

Atlas is a web application to learn about currently running Tor relays.

B

bandwidth authority

To determine a relay's throughput, special relays called bandwidth authorities take periodic measurements of the relays in the consensus.

bridge

Like ordinary Tor relays, bridges are run by volunteers; unlike ordinary relays, however, they are not listed publicly, so an adversary cannot identify them easily. Pluggable transports are a type of bridge that help disguise the fact that you are using Tor.

bridge authority

A special-purpose relay that maintains the list of bridges.

browser fingerprinting

Fingerprinting is the process of collecting information about a device or service to make educated guesses about its identity or characteristics. Unique behavior or responses can be used to identify the device or service analyzed. Tor Browser prevents fingerprinting.

browsing history

A browser history is a record of requests made while using a web browser, and includes information like websites visited and when. Tor Browser deletes your browsing history after you close your session.

C

CAPTCHA

Captchas are a challenge-response test used in computing to determine whether the user is human or not. Tor users are often served captchas because Tor relays make so many requests that sometimes websites have a hard time determining whether or not those requests are coming from humans or from bots.

checksum

Checksums are hashvalues of files. If you have downloaded the software without errors, the given checksum and the checksum of your downloaded file will be identical.

circuit

A path through the Tor network built by clients consisting of randomly selected nodes. The circuit begins with either a bridge or a guard. Most circuits consist of three nodes - a guard or bridge, a middle relay, and an exit. Most onion services use six hops in a circuit (with the exception of single onion services), and never an exit node. You can view your current Tor circuit by clicking on the onion button in Tor Browser.

client

In Tor, a client is a node in the Tor network, typically running on behalf of one user, that routes application connections over a series of relays.

Compass

Compass is a web application to learn about currently running Tor relays in bulk.

consensus

In Tor terms, a single document compiled and voted on by the directory authorities once per hour, ensuring that all clients have the same information about the relays that make up the Tor network.

An HTTP cookie (also called web cookie, Internet cookie, browser cookie or simply cookie) is a small piece of data sent from a website and stored on the user's computer by the user's web browser while the user is browsing. Tor Browser does not store cookies.

cross-site scripting (XSS)

Cross-Site Scripting (XSS) allows an attacker to add malicious functionality or behavior to a website when they shouldn't have the ability to do so.

cryptographic signature

A cryptographic signature proves the authenticity of a message or file. It is created by the holder of the private portion of a public key cryptography key pair and can be verified by the corresponding public key. If you download software from torproject.org, you will find it as signature files (.asc). These are PGP signatures, so you can verify that the file you have downloaded is exactly the one that we intended you to get. For more information about how you can verify signatures, please see here.

D

Dimoni

Un dimoni és un programa informàtic que s'executa com un procés en segon pla, en comptes de fer-ho sota el control directe d'un usuari.

directory authority

A special-purpose relay that maintains a list of currently-running relays and periodically publishes a consensus together with the other directory authorities.

E

xifratge

The process of taking a piece of data and scrambling it into a secret code that can only be read by the intended recipient. Tor uses three layers of encryption in the Tor circuit; each relay decrypts one layer before passing the request on to the next relay.

end-to-end encrypted

Transmitted data which is encrypted from origin to destination is called end-to-end encrypted.

exit

The last relay in the Tor circuit which sends traffic out onto the public Internet. The service you are connecting to (website, chat service, email provider, etc..) will see the IP address of the exit.

ExoneraTor

The ExoneraTor service maintains a database of relay IP addresses that have been part of the Tor network. It answers the question whether there was a Tor relay running on a given IP address on a given date. This service is often useful when dealing with law enforcement.

F

Firefox

Mozilla Firefox is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Tor Browser is built from a modified version of Firefox ESR (Extended Support Release). Firefox is available for Windows, macOS and Linux operating systems, with its mobile version (fennec) available for Android.

firewall

A firewall is a network security system which monitors and controls the incoming and outgoing network traffic. This traffic filter is based on predetermined rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network but it can also be used as a content filter in the sense of censorship. Sometimes people have trouble connecting to Tor because their firewall blocks Tor connections. You can reconfigure or disable your firewall and restart Tor to test this.

Flash Player

Flash Player is a browser pluginfor Internet applications to watch audio and video content. You should never enable Flash to run in Tor Browser as it is unsafe. Many services that use Flash also offer an HTML5 alternative, which should work in the Tor Browser.

fte

FTE (format-transforming encryption) is a pluggable transport that disguises Tor traffic as ordinary web (HTTP) traffic.

G

GetTor

It is a service that automatically responds to messages (Email, XMPP, Twitter) with links to the latest version of Tor Browser, hosted at a variety of locations, such as Dropbox, Google Drive and GitHub.

GSoC

The Tor Project participates in the Google Summer of Code, which is a summer program for university students.

guard

The first relay in the Tor circuit, unless using a bridge. When using a bridge, the bridge takes the place of the guard.

H

hash

A cryptographic hash value is the result of a mathematical algorithm that maps data to a bit string of a fixed size. It's designed as one-way-function which means the value is easy to calculate in one direction but infeasible to invert. Hash values serve to verify the integrity of data.

hidden services

Former name for "onion services", sometimes still in use in Tor documentation or communication.

hop

In Tor terms, a "hop" refers to traffic moving between relays in a circuit.

HTTP

The Hypertext Transfer Protocol (HTTP) is a channel used to send files and data between devices on a network. Originally used to transfer only web pages, it is now relied upon to deliver many forms of data and communication.

HTTPS

Hypertext Transfer Protocol Secure is the encrypted version of the HTTP channel used to transfer files and data between devices on a network.

HTTPS Everywhere

HTTPS Everywhere is a Firefox, Chrome, and Opera extension that makes HTTPS the default on websites that have set up HTTPS but have not made it the default. HTTPS Everywhere is installed in Tor Browser.

I

Internet Service Provider (ISP)

An Internet service provider (ISP) is an organization that provides services for accessing and using the Internet. When using Tor Browser, your ISP cannot see what websites you're visiting.

IP address

An Internet Protocol address (IP address) is a numerical (or alpha-numeric in the case of IPv6) label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. The IP address is the location address of the device, similar to the addresses of physical locations. Tor Browser obscures your location by making it look like your traffic is coming from an IP address that is not your own.

J

JavaScript

JavaScript is a programming language that websites use to offer interactive elements such as video, animation, audio, and status timelines. Unfortunately, JavaScript can also enable attacks on the security of the web browser, which might lead to deanonymization. The NoScript extension in Tor Browser can be used to manage JavaScript on different websites.

K

L

little-t tor

"little-t tor" is one way of referring to tor the network daemon, as opposed to Tor Browser or Tor Project.

M

meek

These pluggable transports all make it look like you are browsing a major web site instead of using Tor. Meek-amazon makes it look like you are using Amazon Web Services; meek-azure makes it look like you are using a Microsoft web site; and meek-google makes it look like you are using Google search.

middle relay

The middle position in the Tor circuit. Non-exit relays can function as either a "middle" or a "guard" for different users.

N

New Identity

New Identity is a Tor Browser feature if you want to prevent your subsequent browser activity from being linkable to what you were doing before. Selecting it will close all your open tabs and windows, clear all private information such as cookies and browsing history, and use New Tor circuits for all connections. Tor Browser will warn you that all activity and downloads will be stopped, so take this into account before clicking “New Identity”. New Identity can also help if Tor Browser is having trouble connecting to a particular site, similarly to "New Tor Circuit for this Site".

New Tor Circuit for this Site

This option is useful if the exit you are using is unable to connect to the website you require, or is not loading it properly. Selecting it will cause the currently active tab or window to be reloaded over a new Tor circuit. Other open tabs and windows from the same website will use the new circuit as well once they are reloaded. This option does not clear any private information or unlink your activity, nor does it affect your current connections to other websites.

network censorship

Sometimes the direct access to the Tor network is blocked by your Internet Service Provider (ISP) or by a government. Tor Browser includes some circumvention tools for getting around these blocks, including bridges, pluggable transports, and GetTor.

NoScript

Tor Browser includes an add-on called NoScript, accessed through the “S” icon at the top-left of the window, which allows you to control the JavaScriptthat runs on individual web pages, or to block it entirely.

nyx

The anonymizing relay monitor (formerly arm, now nyx) is a terminal status monitor for Tor, intended for command-line usage. This is a tool for monitoring the core Tor process on a system, often useful for relay operators.

O

obfs3

Obfs3 is a pluggable transport that makes Tor traffic look random, so that it does not look like Tor or any other protocol. Obfs3 bridges will work in most places.

obfs4

Obfs4 is a pluggable transport that makes Tor traffic look random like obfs3, and also prevents censors from finding bridges by Internet scanning. Obfs4 bridges are less likely to be blocked than obfs3 bridges.

onion address

A standardized internet domain name used by onion services that ends in .onion and is designed to be self-authenticating.

OONI

OONI stands for "Open Observatory of Network Interference", it is a global observation network for detecting censorship, surveillance and traffic manipulation on the internet.

Onion Browser

An iOS app which is open source, uses Tor routing, and is developed by someone who works closely with the Tor Project. Learn more about Onion Browser

onion services

Onion services (formerly known as “hidden services”) are services (like websites) that are only accessible through the Tor network. Onion services offer advantages over ordinary services on the non-private web, including:

Onionoo

Onionoo is a web-based protocol to learn about currently running Tor relays and bridges. Onionoo provides the data for other applications and websites(compass, atlas, etc..) which in turn present Tor network status information to humans.

onionsite

An onionsite is another name for an onion service, but refers exclusively to websites. These websites use the .onion Top Level Domain (TLD).

onionspace

The set of available onion services. For example, you can say "my site is in onionspace" instead of "my site is in the Dark Web."

Operating System (OS)

The main system software that manages computer hardware and software resources and provides common services for computer programs. The most used desktop operating systems are Windows, macOS and Linux. Android and iOS are the dominant mobile operating systems.

Orbot

Orbot is a free app from The Guardian Project that empowers other apps on your device to use the internet more securely. Orbot uses Tor to encrypt your Internet traffic and hide it by bouncing through a series of computers around the world.

Orfox

Orfox is no longer maintained or supported.

To browse the web using Tor on Android, please use the supported Tor Browser for Android app developed by the Tor Project.

P

pluggable transports

Tools that Tor can use to disguise the traffic it sends out. This can be useful in situations where an Internet Service Provider (ISP) or other authority is actively blocking connections to the Tor network.

private key

The private portion of a public/private key pair. This is the key that must be kept private, and not disseminated to others.

proxy

A proxy is a middle man between a client (like a web browser) and a service (like a web server). Instead of connecting directly to the service, a client sends the message to the proxy. The proxy makes the request on behalf of the client, and passes the response back to the client. The service only communicates with and sees the proxy.

public key

The public portion of a public/private key pair. This is the key that can be disseminated to others.

public key cryptography

A public-key cryptography system uses pairs of mathematical keys. The public key can be disseminated widely while its belonging private key is known only by the owner of the key pair. Any person can encrypt a message using the public key of the receiver but only the receiver in possession of the private key is able to decrypt the message. Additionally, the private key can be used to create a signature to proof the identity of the creator of a message or other files. This signature can be verified by the public key.

Q

R

relay

A publicly-listed node in the Tor network that forwards traffic on behalf of clients, and that registers itself with the directory authorities.

S

Satori

It is an add-on for the Chrome or Chromium browsers that allows you to download several security and privacy programs, including Tor Browser, from different sources. You can Install Satori from the Chrome Web Store.

scramblesuit

Scramblesuit is similar to obfs4 but has a different set of bridges.

script

Elements used for offering dynamic/interactive content via websites.

self-authenticating address

The specialized address format of onion addresses is self-authenticating. The format automatically guarantees that the onion address is bound to the key used to protect connections to the onionsite. Ordinary internet domain names require site owners to trust and be approved by a Certificate Authority (CA) for this binding, and they are subject to hijack by the CA and typically by many other parties as well.

server

A device on a network which offers a service, such as file and web page storage, email or chat.

session

A session refers to a conversation between two devices communicating on a network. Using Tor Browser means that your session data will be wiped when you close the web browser.

single onion service

A single onion service is an onion service that can be configured for services that do not require anonymity, but want to offer it for clients connecting to their service. Single onion services use only three hops in the circuit rather than the typical six hops for onion services.

Stem

Stem is a Python (programming language) controller library for core Tor. If you want to control core Tor with python, this is for you.

Sybil attack

The Sybil attack in computer security is an attack wherein a reputation system is subverted by creating a large number of identities, and using them to gain a disproportionately large influence in the network.

T

Tails

Tails is a "live" operating system, that you can start on almost any computer from a DVD, USB stick, or SD card. It aims to preserve your privacy and anonymity. Learn more about Tails.

The Tor Project

The Tor Project can refer to either The Tor Project Inc, a 501(c)3 US nonprofit responsible for maintaining the Tor software, or the Tor Project community made up of thousands of volunteers from all over the world who help create Tor.

third-party tracking

Most websites use numerous third-party services, including advertising and analytics trackers, which collect data about your IP address, web browser, system and your browsing behavior itself, all of which can link your activity across different sites. Tor Browser prevents a lot of this activity from happening.

Tor / Tor network/ Core Tor

Tor is a program you can run on your computer that helps keep you safe on the Internet. It protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. This set of volunteer relays is called the Tor network. Sometimes the software associated with this network is called Core Tor, and sometimes "little-t tor". The way most people use Tor is with Tor Browser which is a version of Firefox that fixes many privacy issues.

Tor Browser

Tor Browser uses the Tor network to protect your privacy and anonymity. Your internet activity, including the names and addresses of the websites you visit, will be hidden from your Internet Service Provider (ISP) and from anyone watching your connection locally. The operators of the websites and services that you use, and anyone watching them, will see a connection coming from the Tor network instead of your real Internet (IP) address, and will not know who you are unless you explicitly identify yourself. In addition, Tor Browser is designed to prevent websites from “fingerprinting” or identifying you based on your browser configuration. By default, Tor Browser does not keep any browsing history. Cookies are only valid for a single session (until Tor Browser is exited or a New Identity is requested).

Tor Launcher

When you run Tor Browser for the first time, you see the Tor Launcher window. It offers you the option to connect directly to the Tor network, or to configure Tor Browser for your connection. In the second case Tor Launcher will take you through a series of configuration options.

Tor log

"Tor log" is an automatically-generated list of Tor’s activity that can help diagnose problems. When something goes wrong with Tor, you may see an option with the error message to "copy Tor log to clipboard". If you don't see this option and you have Tor Browser open, you can navigate to the Torbutton (on the top left of the browser, to the left of the URL bar). Click the Tor button, then open Tor Network Settings. You should see an option at the bottom to copy the log to your clipboard, which you can then paste to a document to show whoever is helping you troubleshoot.

Tor Messenger

Tor Messenger was a cross-platform chat program that aimed to be secure by default and send all of its traffic over Tor. Tor Messenger is not in development anymore. It supported Jabber (XMPP), IRC, Google Talk, Facebook Chat, Twitter, Yahoo, and others; enabled Off-the-Record (OTR) Messaging automatically; and had an easy-to-use graphical user interface localized into multiple languages.

TorBirdy

This extension configures Thunderbird to make connections over Tor.

Torbutton

A button marked by a little green onion to the left of the URL bar. Its menu offers you "New Identity", "Security Settings..." and "Check for Tor Browser Update..." options.

torrc

The core Tor configuration file.

Torsocks

Torsocks allows you to use many applications in a safer way with Tor. It ensures that DNS requests are handled safely and explicitly rejects any traffic other than TCP from the application you're using.

Tor2Web

Tor2web is a project to let users access onion services without using the Tor Browser. NOTE: This is not as safe as connecting to the onion services via Tor Browser, and will remove all Tor-related protections the client would otherwise have.

TPI

TPI is an acronym for The Tor Project, Inc.

tpo

People on IRC often use tpo to abbreviate torproject.org when writing hostnames. For example, trac.tpo is an abbreviation for trac.torproject.org.

traffic

Traffic is the data sent and received by clients and servers.

U

V

W

Web Browser

A web browser (commonly referred to as a browser) is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. Major web browsers include Firefox, Chrome, Internet Explorer, and Safari.

website mirror

A website mirror is an one-to-one copy of a website which you can find under other web addresses. A current list of torproject.org mirrors is available at https://www.torproject.org/getinvolved/mirrors.html.en.

No hi ha res que els desenvolupadors de Tor puguin fer per rastrejar els usuaris de Tor. Les mateixes proteccions que eviten que les persones dolentes frenin l'anonimat de Tor també ens impedeix rastrejar els usuaris.

No,el projecte Tor no ofereix serveis d'allotjament?

Ara mateix, la longitud de la ruta està codificada a 3 punts més el nombre de nodes sensibles de la vostra ruta. És a dir, en casos normals és de 3, però per exemple si accediu a un servei de onion o una adreça ".exit", podria ser més.

No volem encoratjar a les persones a utilitzar trajectes més llargs que això, ja que augmenta la càrrega a la xarxa sense (en la mesura que podem dir) que proporcioni més seguretat. A més, l'ús de rutes de més de 3 pot fer malbé l'anonimat, primer, perquè facilita els atacs dedenegació de seguretat i, en segon lloc, perquè podria actuar com a identificador si només un petit nombre d'usuaris tenen la mateixa longitud de camí.

Molts nodes de sortida es configuren per blocar certs tipus de trànsit per compartir fitxers, com ara BitTorrent. BitTorrent en concret no és anònim sobre Tor.

For sharing files over Tor, OnionShare is a good option.

Tor està dissenyat per defensar els drets humans i la privadesa evitant que ningú censuri coses, fins i tot nosaltres. Odiem que hi ha algunes persones que utilitzen Tor per fer coses terribles, però no podem fer res per desfer-se'n sense que també perjudiquem als activistes de drets humans, periodistes, superviventgs d'abusos i altres persones que utilitzen Tor per a coses bones. Si volguéssim blocar determinades persones d'utilitzar Tor, bàsicament hauríem afegit una porta del darrere al programari, que obriria als nostres usuaris vulnerabilitats, atacs de mals règims i altres adversaris.

Tor està finançat per diversos patrocinadors, incloent agències federals nord-americanes, fundacions privades i donants individuals. Consulteu una llista de tots els nostres patrocinadors i una sèrie de publicacions sobre els nostres informes financers.

We feel that talking openly about our sponsors and funding model is the best way to maintain trust with our community. Sempre busquem més diversitat en les nostres fonts de finançament, especialment de fundacions i particulars.

No recomanem utilitzar Tor amb BitTorrent. Per obtenir més informació, consulteu la nostra publicació de bloc sobre el tema.

Ho sentim molt, però ha estat infectat amb programari maliciós. El projecte Tor no ha creat aquest programari maliciós. Els autors del programari maliciós us demanen que baixeu el navegador Tor probablement per contactar-los de forma anònima amb el rescat que us demanen.

Si aquesta és la primera introducció al navegador Tor, entenem que podríeu pensar que som persones dolentes que habilitem persones encara pitjors.

Però consideri que el nostre programari s'utilitza diàriament per a diversos propòsits per activistes de drets humans, periodistes, supervivents de violència domèstica, denunciants, agents de policia i molts altres. Malauradament, la protecció que el nostre programari pot proporcionar a aquests grups de persones també pot ser maltractat pels criminals i els autors de malware. El projecte Tor no dona suport ni excusa l'ús del nostre programari per a fins maliciosos.

Tor no guarda registres que puguin identificar un usuari concret. Realitzem mesures segures sobre com funciona la xarxa, que podeu consultar a Tor Metrics.

No, no oferim cap servei en línia. Podeu trobar una llista de tots els nostres projectes de programari a la nostra pàgina de projectes.

Vidalia ja no es manté o és suportat. Una gran part de les funcions que Vidalia ofereix ara s'ha integrat al propi navegador Tor.

Here is the simplest possible guide for getting onto IRC and starting to chat with Tor people in real time.

(1) Enter in ​OFTC webchat.

(2) Fill in the blanks:

NICKNAME: Anything you want, but choose the same nickname (nick) every time you use IRC to talk to people on Tor. If your nick is already being used, you will get a message from the system and you should choose another nick.

CHANNEL: #tor

(3) Click Enter

Congratulations! You’re on IRC.

After a few seconds, you will automatically enter #tor, which is essentially a chatroom. It usually includes Tor developers, relay operators and other community members. There are some random people in #tor as well.

You can ask questions here (in the empty bar at the bottom of the screen), and people may be able to answer right away, or there may be a bit of a delay (some people are listed on the channel but are away from their keyboards and record channel activities to read later).

If you want to chat with someone specific, start your comment with their nick (if you know it) and they will typically receive a notification that someone is trying to contact them. Please, don't ask to ask, just ask your question.

You should also consider to use an IRC client.

The #tor-project channel is where Tor people discuss and coordinate daily Tor work. It has fewer members than #tor and is more focused on the work at hand. You are also welcome to join this channel. To access #tor-project, your nickname (nick) must be registered and verified.

Here's how to reach #tor-project and other registered channels. This can be tricky; bring your patience and a cup of your favorite beverage.

Register your nickname

  1. Log onto #tor. See How can I chat with Tor Project teams?

  2. Then, click on the word "Status" at the top left of the screen.

  3. In the window at the bottom of the page, type: /msg nickserv REGISTER yournewpassowrd youremailaddress

  4. Hit enter.

If all goes well, you will receive a message that you are registered.

The system may register you as your nick_ instead of your nick.

If so, just go with it but remember you are user_ and not user.

Every time you log on to IRC, to identify your registered nick, type:

/nick yournick

/msg nickserv IDENTIFY YourPassWord

To verify your nickname

Then, to complete the registration and ultimately gain access to the #tor-project channel, your nickname must be VERIFIED.

  1. To verify your nick, open a new browser window and go to ​https://services.oftc.net/.

  2. Log in with your IRC nickname and password.

  3. Look for the word VERIFIED and log in there. It may appear that nothing has happened. Look at the top of the page, and there will be a column called ACCOUNT.

  4. Click on ACCOUNT.

  5. Click on the small sentence at the bottom of the square that says: Verify account.

  6. Fill out the CAPTCHA that pops up, and click ok.

  7. A tiny message will appear: "Your NickServ account has been verified."

  8. Go back to the IRC webpage where you are logged in and type: /msg nickserv checkverify

  9. Click ENTER

  10. If all is well, you will receive a message that says:

*!NickServ*checkverify

Usermodechange: +R

!NickServ- Successfully set +R on your nick.

Your nick is verified! Hurrah!

Now, to join #tor-project, you can just type:

/join #tor-project and hit enter.

You will be allowed into the channel. If so, Congratulations!

However, if you get stuck, you can ask for help in the #tor channel. You can toggle back and forth between channels by clicking on the different channel names at the top left of the IRC window.
