destructeur on 12:54 PM 07/09/2018: travisjayday You should read the FAQ. The password is "crackmes.one"

mois_Hamappleman on 9:05 PM 03/09/2020: The Sh4ll10 was good, you got with your XOR, But this time it was your tip, i looked at the Stack for an hour, and tried to find some hint or so. Later i thought "frick it" and looked through the code. The 3'th crackme that i did from you and also the first one i solved on my own.(i kinda had solved Sh4ll0 too but thought neg only inverts all bits and tried to subtract 10001100-_o_- ). Thank you;

destructeur on 12:04 PM 03/13/2020: Good job mois_Hamappleman, there are nine crackmes left ;) [spoiler] The idea of the crackme comes from the section 1.9.4 "Noise in the stack" of the book "Reverse engineering for beginners", take a look at https://beginners.re So if you validated the crackme without understanding the principle behind it, I advise you to read the book.
