DarkBlizz

Blizzard should thank Vernam7: because of his crack I decided to buy the game 

Thanks a lot! Next step is to keygen the game itself... Or buy it as soon as it is possible.

Just my two cents: if Blizzard has allowed this to be installed off-line with authentication key then it should be possible to crack the installation without resorting to brute-forcing decryption keys. In other words: it is a matter of simple serial cracking, lots of tutorials are available, for example:

I used to do this back in the day when Soft-Ice was the king but haven't touched any debuggers since then
