Description
An extremely simple crackme for beginners!
If you've managed to crack the program, feel free to post a comment/solution :)
Explanation:
Ok, so there's simply just a 4-digit key that you must figure out in order to unlock the program. But, if you have some reverse engineering skills it should be pretty easy to unlock the program without a key ;)
