View File Poetic AutoIt (string/integer obfuscation) This is a simple CrackMe consisting of an input. The correct input is two stanzas of a particular poem and will reveal a label of the poem title and author upon success. Otherwise, "Try again..." will be displayed. If I'm allowed to be picky, I'm primarily interested in scripted efforts to RegEx analyze strings/integers. Very little effort (as in none) went into hiding the correct string.

View File A crackme with math problem Just run it. It is an interesting math problem. No vm, no obfuscation. You can debug it with dnSpy even Visual Studio. You should use public method inside this crackme to generate a valid hex string and make program output correct string. Submitter wwh1004 Submitted 08/07/2020 Category CrackMe

View File CrackMeBoi I made a custom obfuscator and I haven't made any progress cracking it so please crack the file with my custom .NET obfuscator.

Language : C# Platform : Windows x32/x64 OS Version : Windows 10 Packer / Protector : Modded ConfuserEx + a packer. Description : Basically, just find the key to decode the string. All I will be (probably) using this for is for is to garbage-up some .INI files for my apps to read/write to, so that way there's no plain text. This isn't for hiding some sensitive information lol. Also, if you could, rate the difficulty from 1/10. Thanks! Screenshot : CrackMe.rar
