Verification with GPG (CLI)
To verify the document's cryptographic signature from your terminal:
gpg --import koperateur-pubkey.asc
gpg --verify canary.txtCanary limitations
A warrant canary is a transparency mechanism. It does not guarantee the absolute absence of surveillance, but publicly signals service integrity at a given moment. Failure to renew beyond the expiry date should be interpreted as a warning signal.
Independence and sovereignty
The Quaric Foundation rests on a sovereign, auditable infrastructure with no dependency on any uncontrolled third party. The canary complements this model by providing a continuous, verifiable integrity declaration.
What is a warrant canary?
A public declaration confirming that no secret request for access to data or infrastructure has been received by our technical team.
How do I verify this canary?
The embedded PGP signature lets you mathematically verify that the document comes from Koperateur Consulting's infrastructure and has not been altered. The public key is downloadable above.
What happens if the canary disappears?
The absence, removal or non-renewal of the canary beyond the expiry date may indicate that an external legal constraint prevents our team from publishing it. You should then consider the infrastructure as potentially compromised.
Why use PGP?
PGP is a robust cryptographic standard that lets a document be signed publicly and its authenticity verified offline, without depending on a third party server nor a centralised certification authority.
