Another x64 Linux crackme. Reads input from stdin and tells you if it's correct or not after thinking about it for a second or so. Most of the binary was generated by a custom tool. While it's quite large, it doesn't contain any dead code or unused variables. It also doesn't have anti-debugging features, doesn't play weird games with exception handlers, doesn't modify itself and doesn't even have much control flow to speak of. I'm pretty sure it'll be an absolute nightmare to analyze despite this. And I don't think dynamorio will be of much help with this one. ;)
