newbie question(s)

Im a complete newb when it comes to CO programming. So humor me.. Does CO make any attempt to encrypt packets at all. And does the cipher change between program launches or patches? Or do they just switch the packets around [what code does what] from time to time ?

edit: and btw I did try searching through the forum but couldn't find any info on it.

Ty.

What sort of encryption do they use? I assume it is really crappy like xor...

Was before v.5018. Now they only use the crap xor for login servers. Game servers use blowfish, supplemented by a DH key exchange.

I'm surprised it is even that strong. Any idea what the key length they use is ? I wonder why they didn't at least go with twofish.

32 - 448 bits =P

Initiall 128-bit, afterwards 448 (well, the result of the DH-key exchange, which is 512-bits, but some of it is omitted)
