co je to za komunikator ? Pokud jde o ICQ tak jsou na to ultility. Jinak bych odchytil paket, se kterým se loguje a podival se na stránku, ktera popisuje ICQ Protocol (pokud jde o jiny komunikator.. pak podobna cesta)

"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 ) "

Mozna to ma i v tehle podobe u sebe. Tak ci tak by jsi mel napsat alespon klienta/sit....
