MitM Flaw in Bitchat: Identity Is a Bitchat Challenge
- spr-alex 1y agobitchat has a trivial MITM flaw with the favorite's identity system. i wrote up my thoughts around vibe coding cryptographic security and rolling a new protocol
- NitpickLawyer 1y agoAre there any tell-tale signs of vibecoding in the code base? Or are we at the point where we're using it as a pejorative for bad code?
- spr-alex 1y agoi am not using it as a pejorative here, I am pretty sure that is the case for this code base, as every block has a comment describing the code that immediately follows also i do not doubt jack's cryptography and encryption understanding, so this particular MitM flaw is almost certainly not what human steering would put together. x25519 APIs makes it both easy and simple to do identity persistence correctly, the code simply doesn't use the identity key cryptographically.
- zith 1y agoI guess "don't roll your own crypto" is as valid as ever.

- d00mB0t 1y agoSounds like a feature and not a bug. 'Secure' but with enough holes for three letter agencies.
