Myth is an ADD/SUB encoder for generating alphanumeric shellcode. It takes user-supplied shellcode and outputs the assembly instructions, in a Python-friendly format, necessary to push that shellcode onto the stack by iteratively manipulating the EAX register.
This was mainly an excercise in exploring C++ and trying to make something useful at the same time. Hopefully some CTP/OSCE students get some use out of the tool.
Inspired by Slink and z3ncoder.
Myth accepts shellcode input in the following formats: 545b81ebb90d0000ffd3 or 545B81EBB90D0000FFD3.
g++ myth.cpp -o myth
