- tptacek 12y agoIt's been awhile since I looked at anything in Telegram and I forget what MAC they use. That diagram makes it look like instead of a MAC, they're using a simple digest of the message --- which is not a MAC.
- owenmarshall 12y agoHeh. I just looked again and had misread their specs: I thought the shared secret went into their SHA-1. You are correct, they just take a digest. So I can make any message look OK just by hashing the plaintext. Heh. Wonder what that KDF looks like...
