Description

this is the first version of arbchal (beta v0.1) im still working on it but i need a solid writeup on it since it exceeds my RE level and i cannot solve it myself anymore, it is solvable 100%. type: Keygenme CTF you can make a keygen, you can patch, you can do whatever you want but the goal is to get the correct flag and i think a lot of highly skilled ppl will be intrested in the methods i used (excluding the basics like custom vm's, runtime decryption blah blah, some of the methods are "kind of original", i never seen them but they were probably used by someone but 100% they are unusual) i just hope for a quick and worthy writeup on it so i can continue working on it and improving it even more (making it a nightmare aka my masterpiece)
