Services onion

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

Image of an onion An onion means:

  • The Onion Service is served over HTTP, or HTTPS with a CA-Issued certificate.
  • The Onion Service is served over HTTPS with a Self-Signed certificate.

Image of an onion with a red slash An onion with a red slash means:

  • The Onion Service is served with a script from an insecure URL.

Image of an onion with a caution sign An onion with caution sign means:

  • The Onion Service is served over HTTPS with an expired Certificate
  • The Onion Service is served over HTTPS with a wrong Domain
  • The Onion Service is served with a mixed form over an insecure URL

Si vous n’arrivez pas à accéder au service onion que vous souhaitez, assurez-vous d’avoir saisi correctement l’adresse onion de 16 caractères ou le nouveau format de 56 caractères. Même une seule petite erreur empêchera le Navigateur Tor d’accéder au site. Si vous ne parvenez toujours pas à vous connecter au service onion, veuillez réessayer ultérieurement. Il pourrait y avoir un problème temporaire de connexion ou les opérateurs du site pourraient avoir permis qu’il soit hors ligne, sans avertissement.

You can also ensure that you're able to access other onion services by connecting to DuckDuckGo's onion service.

Les services onion permettent aux gens de naviguer et aussi de publier dans l’anonymat, même de publier des sites Web anonymes.

Onion services are also relied on for metadata-free chat and file sharing, safer interaction between journalists and their sources like with SecureDrop or OnionShare, safer software updates, and more secure ways to reach popular websites like Facebook.

Ces services utilisent le domaine de premier niveau à usage spécial .onion (au lieu de .com, .net, .org, etc…) et ne sont accessibles que par le réseau Tor.

When accessing a website that uses an onion service, Tor Browser will show at the URL bar an icon of an onion displaying the state of your connection: secure and using an onion service.

Les sites Web qui ne sont accessibles que par Tor sont appelés « onions » et se terminent par le domaine de premier niveau .onion. For example, the DuckDuckGo onion is https://3g2upl4pq6kufc4m.onion. Vous pouvez accéder à ces sites Web en utilisant le Navigateur Tor. L’adresse doit être partagée avec vous par l’hôte du site Web, car les onions ne sont pas indexés dans les moteurs de recherche de façon habituelle, comme les sites Web ordinaires le sont.

Onion-Location is a new HTTP header that web sites can use to advertise their onion counterpart. If the web site that you're visiting has an onion site available, a purple suggestion pill will prompt at the URL bar saying ".onion available". When you click on ".onion available", the web site will be reloaded and redirected to its onion counterpart. At the moment, Onion-Location is available for Tor Browser desktop (Windows, macOS and GNU/Linux). You can learn more about Onion-Location in the Tor Browser Manual. If you're an onion service operator, learn how to configure Onion-Location in your onion site.

An authenticated onion service is an onion service that requires you to provide an authentication token (in this case, a private key) before accessing the service. The private key is not transmitted to the service, and it's only used to decrypt its descriptor locally. You can get the access credentials from the onion service operator. Reach out to the operator and request access. Learn more about how to use onion authentication in Tor Browser. If you want to create an onion service with client authentication, please see the Client Authorization in the Community portal.
