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

Dunno if anyone's seen anything like this before. If I share a serial though, it'll mostly spoil the fun, so have at it. I think this one will take a little detective work. EDIT: I might want to attach it...

You should find out the correct UserName and the RegCode.It's Very Easy for you .And It need .Net runtime SuperSerialMe.rar

Hey all, This is my first and probably my only KeygenMe. I wrote for a friend who's into VB apps (I haven't written VB6 in years). It's an easy algo, I just tried to eliminate sting searches and compares to show there are others ways to get to the routine. For anyone who keygens VB apps this should be pretty simple. It's not protected & compiled in native code. Have fun. Let me know what ya think of it KeygenMe#1.rar

After some coding for my team, I got an idea abt a type of protection. I did my best to implement it in here. Its not very hard, but you must understand the math involved in it Best OF LUCK Regards KKR Download the challange from attachment : TERMiNATOR.rar .:Solved By :. 1) Saduff
