Serviços Onion

Ao navegar em um serviço Onion, o Navegador Tor exibe diferentes ícones de cebola na barra de endereço, indicando a segurança da página da web atual.

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

Caso você não consiga acessar o serviço onion desejado, certifique-se de ter digitado corretamente os 16 caracteres, ou 56 caracteres no novo formato, do endereço onion: até mesmo um pequeno erro impedirá o Tor Browser de acessar o site. Se você ainda está inabilitado de se conectar ao serviço onion, por favor tente de novamente mais tarde. Pode haver um problema de conexão temporário ou os operadores do site podem ter permitido que ele ficasse offline sem aviso.

Você também pode certificar-se de que é possível acessar outros serviços onion conectando-se ao serviço onion do DuckDuckGo.

Os serviços onion permitem que as pessoas não só naveguem, mas também publiquem anonimamente, inclusive através da edição de websites anônimos.

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.

Esses serviços usam o domínio de nível superior (TLD) de uso especial (em vez de .com, .net, .org, etc.) e só podem ser acessados pela rede 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.

Os sites que só podem ser acessados por meio do Tor são chamados de "onions" (cebolas) e terminam com .onion. Por exemplo, o serviço onion DuckDuckGO é https://3g2upl4pq6kufc4m.onion. Você pode acessar esses sites usando o Tor. Os endereços devem ser compartilhados com você por quem hospeda seu website, como onions não são indexados nos mecanismos de pesquisa na maneira típica que os websites normais são.

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.
