Titanium (Python Obfuscator)

By Nqndi

This is my first crackme, so I may have screwed up some things, but overall it should be a fun challenge. The file is protected with my own packer/obfuscator, Titanium, and compiled with pyinstaller. Read the readme before reversing.

Tricky

By LoLLo90

Goals:
Bronze - Patch the crackme to show the correct message
Silver - Bronze + explain what is happening
I don't know why Windows Defender is giving a false positive. My past here should prove I am not here to harm anyone.
I only used Appfuscator for renaming. I checked the file and I did not see any other obfuscation or anything annoying automatically inserted by Appfuscator (like outline method calls).
Please extract all the files in a folder to make the exe work properly.
Let's fight!

CheckMePlease

By CodeExplorer

This crackme is created with Qt v4.8.4,
The goal of this crackme is to make the CheckBox checked,
not to only pass the check when the Check button is pressed.
There is also the options of creating an program which will change the state of CheckBox.
I don't think is trivial task: I can't even enumerate windows.

This has an anti-debugger which will constantly look for strings that'll contain the name of debuggers such as De4dot and more..

A Crackme with Math Problem

By wwh1004

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.

Poetic AutoIt (string/integer obfuscation)

By SimplyMercurial

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. The script was merely passed-through a self-made obfuscator.
Full disclosure: It contains rudimentary debugger and compilation checks which, if failed, falls into a while loop with a one second sleep (harmless). But, as stated above, this isn't the focus of what I'm after.

CrackMeBoi

By Ninjego1

I made a custom obfuscator and I haven't made any progress cracking it so please crack the file with my custom .NET obfuscator.
Do not use OllyDbg or any software of that kind, you can use Mega Dumper and other tools similar.
