dis2xasm

Convert Python's dis disassembly output to xasm format so that you can use the xasm tool to get the assembly results (in .pyc).

No more worrying about tearing Python bytecode text in CTF! ^0^/

dependencies

python3 -m pip install xasm xdis

usage

python3 dis2xasm.py chal.txt

or use it in Python:

>>> from dis2xasm import dis2xasm
>>> dx = dis2xasm("bytecode", (3, 8)) # "bytecode" is the bytecode's filename
>>> dx.run()
>>> dx.write("bytecode.pyasm") # custom output filename
[+] bytecode.pyasm has been written!
>>> dx.xasm2pyc() # use xasm to get .pyc
Wrote Python 3.8 bytecode file "xasm_bytecode.pyc"; 46934 bytes.

And then you can use some decompiler like decompile3 or pycdc to get its source code.
