I've never posted any of my keygenmes here so I thought I'd throw this one up to see if I can get a solution for it. Rules: Keygen and serial are the only valid solutions. No patching/Selfkeygenning etc.. Cheers, Krip KeyGenMe4.rar

Since this is my tenth KeygenMe, it has to be Very Hard. No, I did not use any cryptos, but it is protected with hardcore math. Note: You will find a MD5 reference, but MD5 is only used in serial checking. Rules: Patching is not allowed! Accepted Solutions: Serial (Silver) Self-Keygen (Silver) Keygen (Gold) Solved by: 1.

Here is an unpackme of TheMida 2.0.8.0 It is similar to previous one, except that it is not hardware locked, so should be easier to unpack. The only thing is that it has a RISC VM, so it will be harder to dump. Goal is just to upack it. Good luck. TheMida_2080_unpackme.zip

hello Can you keygen this file? It's too hard thanks CrackMe05.zip

First of all, this isn't my crackme. This is Sharpe's from Crackmes.de. It took me a little while to solve it, and when I did, I was very pleased with the programming and programmer. It's a very good crackme! I warn you though, the difficulty is a little under-rated. Enjoy! -Cobrasniper555 eight.zip

Warning: DONT CHANGE STRINGS! download and extract all files and then run crackme.bat file. for run this crackme you NEED DOT NET FRAMEWORK 2.0 or higher. Thanks a lot CrackMe_By_Surpriser_V1.zip

This is my eighth KeygenMe. Previous ones are too simple. Rules: Patching is too easy Serial fishing is also too easy Only solution is a stand-alone keygen. Self-keygenning is allowed when you can't make a stand-alone keygen. Solved by: 1. ::: - phpbb3 - ::: - Keygen 2. MA1201 - Keygen Register_Me__8.zip
