    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.

    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.

    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

You have to bypass the registration and get rid of the NAG on the program to make the program think it's valid.

Screenshot : To download, download the zip and run Target.exe. The patcher will show it's a virus but don't worry it's not. It shows it's a bad program because of it being a hacktool, so please disable your AV or add it in exclusi…
