Magic token (authentication request)
When the user successfully connects to the server, the user's machine XORs the
debug token and 1129076036
. For example, 0x434c5544
, ASCII code of “CLUD,” to get the magic token. It then
sends a single line of this magic token to the server as an authentication request. The server
checks its correctness. If it is in error, then the connection is immediately closed.
For example, with a debug token 858680469
, the magic token is
1885485521
because 858680469 XOR 1129076036 =
1885485521
.
