This is the first SNAC sent by the client when authorizing via BUCP used for requesting a challenge. The server should reply with [[Protocols/OSCAR/SNAC/BUCP__LOGIN_REQUEST|BUCP__LOGIN_REQUEST]] containing the aforementioned challenge, which will be used for hashing the password later on.
This is the first SNAC sent, by BUCP clients, right after the FLAP versions are exchanged. It is, obviously, used for requesting a challenge, of which the server replies with [[Protocols/OSCAR/SNAC/BUCP__CHALLENGE_RESPONSE|BUCP__CHALLENGE_RESPONSE]], with the challenge they requested.
