hi guys,thought I’d ask around here to see if there’s any of the sort around. At a high level, I’m looking for a messaging app that is secure and that I don’t have to “trust” third parties.Requirement:- I own my PKI. Full control over my own private key. Full control over my public key and revocation list.- Forced finger print verification. I do not trust any one else other than me to sign / verify.- Open source. That I can audit and compile my own app in an environment I trust.Lesser requirement:- Tor / onion routing / PFS etc- Anything else is icing on top, but would be happy to be enlightened on what other aspects I should be aware of.?????? Thanks in advance.
