LeaKissnerCryptography is a tool for turning a whole swathe of problems into key management problems. Key management problems are way harder than (virtually all) cryptographers think.

@leak nothing a pad of one time keys and a diplomatic bag can't solve 😆​
@tiraniddo Mastodon is secure, right?

@leak even if its public as long as you used a suitably long passphrase to encrypt the private key then it's secure. This solves the key distribution problem, because as everyone knows distributing passphrases is a completely different problem which I assume has been solved by now.
