Auth

Namespace: ClientToChannel  ·  Opcode: 0x0002 (2)

Second-stage channel auth handshake sent after a successful Login reply. The body carries a 40-character hex hash that the retail client computes client-side; the server does not interpret it.

Fields

Field	Type	Modifiers	Description
Hash	string	lensz=2, encoding=utf8	40-character ASCII hex string, always exactly that length on the wire. The server should not interpret the value — it's preserved only because the client refuses to proceed if the packet shape is wrong.
