The crypto game has now been taken so far by the Telegram Application and that too because of great reasons. B has to choose its value of b and g_b without knowing the true value of g_a, so that it cannot try different values of b to force the final key (g_a)^b to have any specific properties (such as fixed lower 32 bits of SHA256(key)). The parameter recent_received_mask is a 32-bit mask, used to track delivery of the last 32 packets sent by the other party. Telegram has no limits on the size of your media and chats.

This document describes encryption in voice and video calls as implemented in Telegram apps with versions 7.0 and above. This is because instead of the standard Diffie-Hellman key exchange which requires only two messages between the parties: we use a three-message modification thereof that works well when both parties are online (which also happens to be a requirement for voice calls): The idea here is that A commits to a specific value of a (and of g_a) without disclosing it to B.

We have moved Whatsapp from #4 to #7 as a result. Otherwise, the seq values of all incoming messages are memorized and max_received_seq is adjusted. Party A will generate a shared key with B -- or whoever pretends to be B -- without having a second chance to change its exponent a depending on the value g_b received from the other side; and the impostor will not have a chance to adapt his value of b depending on g_a, because it has to commit to a value of g_b before learning g_a. Keys are only generated once. The Diffie-Hellman key exchange, as well as the whole protocol used to create a new voice call, is quite similar to the one used for Secret Chats. The resulting data packet is sent by UDP either directly to the other party (if P2P is possible) or to the Telegram relay servers (reflectors).
