OK guys, I'm glad to hear some of You have found it useful. About tools: I'm not sure all the tools I'm using are free to distribute but if You have strong reasons... why not?
Get ready for cryptographic intro I'll post during 1-2 days. I've chosen ExeShield as a target because it uses Rijndael, SHA and MD5. Moreover it's protected with Xtreme Protector. Yeah, I was a bit surprised too. As far as I know, Xtreme Protector is the hardest one, so prepare for a lot of fun.
I could post it today, but during writing, it has growed to more than 20kb! I must cut out the Xprotector subject because it's too big, and the way I've played with it was not so birght (I don't think You want to write a SoftIce macro which patch over 100 bytes).
What You'll get is a cryptographic intro which will show You the way the most popular algorithms are working (the principles) and how keygenrators are builded. After reading You will be able to keygenerate ExeShield without touching it's code or changing anything inside the file .

Regards.
