Posted May 7, 20187 yr Difficulty : 2 Language : .NET Platform : tested on windows 10 OS Version : All Packer / Protector : Enigma and custom obfuscation (Without constant encryption) Description : So, the goal of this Keygen Me is to obviously create a keygen. Your keygen should create a "KEY" file which will contain data which will be checked by the application. The application takes the key file as input (Drag and drop). Provided with the application is a sample key file which contains a valid key. Create a keygen which will create other valid key files. Screenshot : CrackMe.rar

October 13, 20186 yr Wasn't that hard. 1. Dump the assembly. Open it in x64dbg Break on the entrypoint of clr.dll Dump with MegaDumper 2. Deobfuscate it. For this I wrote a program that I attached below It will deobfuscate the assembly and we can run it/debug it as we please 3. Writing a keygen. While I was reversing, I found a formula that makes this really easy: :(1),#{num1}:(2),#{num2}:(3),#{num3}:(4),#{num4}:(5),#{num5}:(6),#{num6}:(7),#{num7} You just generate a random string that when you add up the characters of it, you receive 662 as the sum. Encrypt it using the Aes thing, just copy paste from dnSpy Write it to a file 4. Done UI.: The large filesize of the keygen is due to the music...:) enjoy Keygen.exe TheCrippledModderDecryptor.exe Edited October 13, 20186 yr by xSilent
