Client use this packet in FLAP channel 0x01 based authorization
[[Protocols/OSCAR/Sign_On|sequence]]. So client should send it
on FLAP channel 0x01. Server should reply via [[Protocols/OSCAR/Sign_On/FLAP#FLAP_FRAME_SIGNOFF|srv_cookie]] packet, containing BOS address/cookie or via
[[Protocols/OSCAR/Sign_On#From_Aleksandr_Shutko:_AUTH_FAILED:_server_authorization_failed_response|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 (<font size=2 color=blue>
0xF3, 0x26, 0x81, 0xC4, 0x39, 0x86, 0xDB, 0x92,

This is for the FLAP-level sign on method. This is the oldest method of sign on, used prior to AIM 3.5. This refers to the FLAP__FRAME_SIGNON authentication method for a user to authenticate to the network. This works similar to, but is not the same as, FLAP__FRAME_SIGNON sequences used to connect to BOSS and other services.

Sequence

Below is a table laying out the sequence, which is further detailed in the sections below. Keep in mind that all of the packets are FLAP packets, and thus only the data is discussed.

Origin Name Length Value Note
Host FLAP_VERSION 4 00 00 00 01 Always 0x01
Client FLAP_FRAME_SIGNON blob xx .. TLV chain containing authentication information
Host FLAP_FRAME_SIGNOFF blob xx .. TLV chain of either BOSS or error information

FLAP_FRAME_SIGNON

X

FLAP_FRAME_SIGNOFF

X

Clients are allowed to, but not required to, send their own empty FLAP_FRAME_SIGNOFF after receiving this one.

Next steps


From Aleksandr Shutko: 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 )
