Below is the whole exchange in between the 2 interacting events, the Customer (A) as well as the Callee (B), with the Telegram servers (S). An implements messages. get, Dh, Config to learn the 2048-bit Diffie-Hellman prime p and generator g.
A picks an arbitrary worth of a, 1 < a < p-1, as well as calculates g_a:=power(g, a) mod p (a 256-byte number) as well as g_a_hash:=SHA256(g_a) (32 bytes long). An invokes (sends to server S) phone. request, Call, which has the area g_a_hash: bytes, amongst others. For this telephone call, this area is to be full of g_a_hash, g_a itself.
This upgrade, besides the identity of An and also other relevant specifications, contains the g_a_hash area, loaded with the worth acquired from A.
