downloadintsig's 64bit_Confusion

Download 64bit_Confusion.tar.gz, 3 kb

This crackme was written in Gentoo Linux for AMD64. It is a 64 bit
ELF executable object.
This crackme runs a series of values through its poor algorithm
and checks your key (argv[1]) against that algorithms output.
The values are hard coded, it shouldnt be too hard to figure out.
The point of this crackme is to mislead you down the wrong path.
- Section header remains in place
- Anti ptrace()
- Misleading instructions (poor obfuscation)

NO patching :)

Difficulty: 2 - Needs a little brain (or luck)
Platform: Unix/linux etc.
Language: C/C++
