i started a (very niche) private messaging protocol & little CLI app demo. i’m no security expert, so any feedback or questions would be appreciated.
the gist is an ephemeral message exchange without identities. the goal is ultimate deniability.
the interesting (and weird) part is that messages are encrypted but not authenticated. this means an imposter could show up if they know the shared secret. otoh this means you can deny anything you say.
ooh, i’ll have to think through it, but it sounds like that’d add message integrity without sacrificing deniability. also wouldn’t be much to add. appreciate the feedback!
