What is Purplix Canary?

Purplix Canary is a free & open source warrant canary tool what helps you to build trust with your users.

It allows you to inform users cryptographically if your site has been compromised, seized or raided by anyone.

How does it work?

Site verification

Purplix uses DNS records to verify the domain the canary is for, giving your users confidence they are trusting the right people.

Canary signatures

Each domain is associated with a unique key pair. The private key is generated locally and securely stored within the owner’s keychain. When a user visits a canary from a specific domain for the first time, their private key is used to sign the public key. This signed version of the public key is then automatically employed for subsequent visits, effectively mitigating man-in-the-middle attacks and ensuring the trustworthiness of canary statements from the respective domain.

Files

Canaries can include signed documents to help users further understand a situation.

Notifications

Users are automatically notified on the event of a new statement being published.

    Wikipedia does claim that patriot act subpeonas can penalise any disclosure of the subpeona. But i am not a lawyer, and afaik this is untested (or at least undisclosed :/ )

    https://en.m.wikipedia.org/wiki/Warrant_canary

    Some subpoenas, such as those covered under 18 U.S.C. §2709© (enacted as part of the USA Patriot Act), provide criminal penalties for disclosing the existence of the subpoena to any third party, including the service provider’s users.

    In September 2014, U.S. security researcher Moxie Marlinspike wrote that “every lawyer I’ve spoken to has indicated that having a ‘canary’ you remove or choose not to update would likely have the same legal consequences as simply posting something that explicitly says you’ve received something.”

    I think my point is that a gag order with a long time out essentially kills the canary, even if it doesnt affect the vast majority of the services users.

    Thanks for your response though, I appreciate the additional information.
