clone keygenme by haggar
==================

This is simple but (I hope) not dumb keygenme for begginers. Algo is in asm, very clear (if you remove junk in second part) and easy to understand.

Find more info in readme.rtf inside.

Tested only on XP Pro SP1. Good luck.

Difficulty: 1 - Very easy, for newbies
Platform: Windows
Language: Assembler

Well , I tought that it's level 2 crackme but moderators change it to 1. This is second version, first was packed (and rejected due to that) and I throved some obfuscation in it, but after uploading new version I removed obfuscation and packer.

l0calh0st, my origional breakpoint was at 004011E7, the call to GetDlgItemTextA.
Im a newbie to keygenning but ive suprisingly managed to follow this through without a problem... the only thing im unsure on is exactly how shl works. How come 'shl ebx, 04' only seems to shift once to the left, and not 4 times :\.

I wrote a tutorial for the packed version of the KeyGen, and I especially liked the obfuscation part; it looks hard but is pretty harmless; nice !
