Garantia do canário

substantivo

1… Um pequeno pássaro canoro da família dos fringilídeos, Serinus canaria domestica, nativo de ilhas do Atlântico Norte.

2… Um mecanismo para testar a segurança de alguma coisa, remontando ao uso de canários em minas de carvão para detectar gases venenosos e prever colapsos. Quando o canário morria, era hora de sair da mina. Mais recentemente, alguns provedores de serviços on-line têm empregado o termo para se referir a uma declaração, atualizada regularmente, de que o provedor não foi sujeitado a certos processos legais. Se a declaração não for atualizada no tempo esperado, pode-se inferir que a garantia do canário não é mais válida.

Riseup positively confirms that the integrity of our system is sound: all our infrastructure is in our control, we have not been compromised or suffered a data breach, we have not disclosed any private encryption keys, and we have not been forced to modify our system to allow access or information leakage to a third party.

This canary will be re-signed on the following dates:

* February 1
* May 1
* August 1
* November 1

We will include a link to a recent news article[1] in each update to establish that the signature was not pre-generated. 
 
h2. Frequently asked questions

Q: Are you compromised by law enforcement?

A: No. We have never permitted installation of any hardware or software monitoring on any system that we control; law enforcement has not taken our servers; does not, and has never had access to them. We would rather stop being Riseup before we did that.

Q: Couldn't the government just make you say that?

A: Forced speech is actually quite rare in the US legal context. It's usually only in cases of consumer protection where the government has been successful in compelling speech (e.g. forced cigarette warnings). Nevertheless, no they aren't forcing us to say anything.

Q: Why didn't you update your canary on time in the winter of 2016?

A: The canary was so broad that any attempt to issue a new one would be a violation of a gag order related to an investigation into a DDoS extortion ring and ransomware operation[0]. This is not desirable, because if any one of a number of minor things happen, it signals to users that a major thing has happened.

Q: Why does the new Canary not mention gag orders, FISA court orders, National Security Letters, etc?

A: Our initial Canary strategy was only harming users by freaking them out unnecessarily when minor events happened. A Canary is supposed to signal important risk information to users, but there is also danger in signaling the wrong thing to users or leading to general fear and confusion for no good reason. The current Canary is limited to significant events that could compromise the security of Riseup users.

Instruções de verificação

Você deve baixar a chave GPG do Riseup e verificar o identificador da chave. Então, siga estes passos para conferir a declaração:

1. Baixe a garantia do canário assinada.

2. Execute este comando em um terminal:

    gpg --auto-key-retrieve --verify canary-statement-signed.txt
   

3. A saída deve ser parecida com o seguinte (lembrando que a data será diferente, dependendo de quando a garantia foi assinada):

    gpg: Signature made Mon 27 Jul 2020 07:57:58 PM -03
    gpg:                using RSA key 4E0791268F7C67EABE88F1B03043E2B7139A768E
    gpg:                issuer [email protected]
    gpg: Good signature from "Riseup Treasurer [email protected] [unknown]
    gpg:                 aka "Riseup Networks [email protected] [unknown]
    gpg: WARNING: This key is not certified with a trusted signature!
    gpg:          There is no indication that the signature belongs to the owner.
    Primary key fingerprint: 4E07 9126 8F7C 67EA BE88  F1B0 3043 E2B7 139A 768E
   

Confirme se a saída diz “Good signature” e se o ID da chave é o mesmo que você verificou aqui, mais cedo.. Se o texto estiver diferente, as informações não são confiáveis.

A não ser que você tenha tomado medidas explícitas para construir um caminho seguro à chave da Riseup Collective, você deve ver uma mensagem de aviso similar a:

```
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
```

Mesmo assim você ainda deve ver “Good signature”.
