«We have introduced a publicly signed warrant canary for Joplin.
A warrant canary is a regularly updated statement confirming that, as of the stated date, the project has not received secret legal orders, gag orders, or demands requiring the introduction of backdoors into the software or its infrastructure».
- science4sail 7mo agoI never really understood warrant canaries. Wouldn't they be still vulnerable to rubber-hose cryptanalysis? An attacker could coerce you to continue updating your canary as if nothing had happened.
- HWR_14 7mo agoIn the US you can legally be compelled to keep certain warrants a secret. They can not legally compel you to make a statement, even if the lack of a statement reveals a warrant's existence.
- Permik 7mo agoAssuming US, I think that the gov't can't actually compel speech from an entity e.g. force to keep signing the canary. Warrant canaries are the way entities can circumvent the narrow case where the gov't actually can restrict your free speech, by creating a case where your lack of speak is telling. By this framework we can then come around again to the first point.
- bombcar 7mo agoThe trick is they can just take over maintaining the canary themselves after black-bagging you. But in general the idea works - in theory.
- gary_0 7mo agoThe point of a canary is that it's cryptographically signed, and it's possible to set up a duress passphrase that will delete the key when entered, so if everything works correctly an unauthorized party can't keep posting signed canaries.
- metalcrow 7mo agoYes, but usually something like that leaves other signs. If men with guns take away a lot of people in your company in theory other people will notice.
