Description

This ain't much. It's just a tester for a new random number generator algorithm based on some initial conditions(data.evl). You have to try and crack the algorithm. I expect both mathematical based solutions from nerds and also RE based solutions. For RE, you'll have to write a keygen that uses the same data.evl to generate the next number(replicate the algorithm). Main challenge for RE will be finding the algorithm. It's not too hard as it's a L2. Looking forward to rare but nerdy solutions. NO PATCHING ALLOWED! If you have any problems, contact me at PranavAppu007 at crackmes.one discord. Thanks.
