KeyGenMe #1 :: VB :: Difficulty : 3

KeyGenMe Location : KeyGenMe #1 @ Crackmes.de
Solution Location : Not Solved Yet


So, here is my first KeyGenMe. It's coded in VB 6.0. Features :
(*) NOT Packed
(*) NOT Encrypted
(*) Nice GUI with Color Code + License Key protection

The Rules :
(*) NO Patching
(*) NO Brute-forcing

The Tasks :
(*) Find algorithm for key and color calculations.
(*) Make KeyGen to generate key and color code for a given user-name.
[ The program accepts a particular color out of 9 colors for each user. The 9 colors are : RED, GREEN, BLUE, YELLOW, CYAN, MAGENTA, BLACK, WHITE, GREY. So, either your KeyGen can show the color or it can just name it. Particularly for C/C++ programmers, you can just display the color name. ]
(*). Write a tutorial. ;)
