SqexArg
Encoded Process Argument
Upon launching the game, the retail launcher passes handful of information (e.g. login token, client language, etc...) to the game that usually looks like this:
1
//**sqex0003VGhpcyBpcyBqdXN0IGZvciBleGFtcGxlIHB1cnBvc2U7IGl0IGFjdHVhbGx5IG5ldmVyIGxvb2sgbGlrZSB0aGlzA**//

Encoding Process
- Encrypt UTF-8 plain text using Blowfish; you need to pad the buffer with zero as needed
- Key is GetTickCount() & 0xFFFF_0000
- Block cipher mode of operation is ECB (yes, you read it right.)
- Format it as
//**sqex0003{base64}{checksum}**//
Checksum
Pseudocode
1
char[] ChecksumTable = {
2
'f', 'X', '1', 'p', 'G', 't', 'd', 'S',
3
'5', 'C', 'A', 'P', '4', '_', 'V', 'L'
4
};
5
6
char GetChecksum(uint key) {
7
// mask the nibble we're looking for
8
var value = key & 0x000F_0000;
9
10
return ChecksumTable[value >> 16];
11
}
