http://crackmes.de/users/the_binary_auditor/the_binary_auditor_splish_1/ There are solutions but none of them really explained how they mathematically did it. It is suppose to satisfy the following condition: serial=username+10*7 But why? Can someone explain it in more detail using the hashes formulas? Sorry for being nub Also, why is 7 used? I am doing a level 1 or 2 keygen on crackmes.de that has already been solved. However, I do not want to look at the solution because I will be cheating myself and I would not have learned anything. Here is what the keygen basically does: Create hash of username: int v = 0; do { v = ( i ^ username[i] % 10 ) + 2; if( (_BYTE)v &g…

Now I am enough to solve it... Thanks all tsrh.team.trial.keygenme.1.zip

Not an easy crackme, the code is made of the 5-year-old-part, 2-year-old-part and a recently-added-part, i hope you'll like it. The best solution would be the name/key pair, but i can set no restrictions, as it is in real life. (Simply redirecting the wrong key proc to the right key proc is like writing your own code, so it is disallowed:)) And, this one wants a lot of your resources, so you better don't try to solve it while running something else /*I guess, that with everything closed it must be ok everywhere - it worked correct even on the old 633Mhz Celeron. Algorithm can be understood anyway*/ So, as it is said, close all other programs and crack it! Good luck…

Hi guys, This is a device driver compiled for 32 bit systems and incorporates virtualized instructions, encrypted strings, and every other common protection routine provided by VMProtect 2. The unpacked driver must be fully loadable and viewable with tools such as IDA. This is not your run of the mill unpack, and if you require more information just post here. I had to upload to my box.net account, hope this is ok; />http://www.box.net/shared/x17h8v0nzv
