Description

The algorithm itself here is very simple (not even 100 lines of code). But I think the obfuscation cranks the difficulty up quite a bit. If you want to learn about deobfuscation techniques and how to deal with stuff like this in general this is for you. EDIT: There is a little mistake in the code (I used xor intead of or in one place), because of that more rhan a single flag gets accepted. Depending on how you solved the algorithm your flag might get accepted by the application but is not the one that I intended. If you have a flag that gets accepted into the crackme but not on the website send me a message. Sorry for the inconvenience Since auto flag validation is on there are no comments, so if you want to contact me: Telegram: @breslau10 Discord: zydak2137
