CLI_IDENT: client authorization request (channel 0x01)

CLI_IDENT

Client use this packet in FLAP channel 0x01 based authorization sequence. So client should send it on FLAP channel 0x01. Server should reply via srv_cookie packet, containing BOS address/cookie or via auth_failed packet, containing error code.

Passwords are roasted when sent to the host. This is done so they aren't sent in "clear text" over the wire, although they are still trivial to decode. Roasting is performed by first xoring each byte in the password with the equivalent modulo byte in the roasting array ( 0xF3, 0x26, 0x81, 0xC4, 0x39, 0x86, 0xDB, 0x92, 0x71, 0xA3, 0xB9, 0xE6, 0x53, 0x7A, 0x95, 0x7C )
