Hello, this is my first CrackMe, but I think is very hard because I haven't seen this method yet. Sorry for 2mb file, but linking is very much size. There is a function which returns true/false for Login, patch it to true and you did it. Might be super easy or super hard, idk! Good luck CrackMe.zip
