- constgrep: Tool for finding constants defined in header files.
- cyclic: De Bruijn sequence generator and lookup tool.

Requirements
pwntools is best supported on Ubuntu 12.04 and 14.04, but most functionality should work on any Posix-like distribution (Debian, Arch, FreeBSD, OSX, etc.).
Most of the functionality of pwntools is self-contained and Python-only. You should be able to get running quickly with:
|
1
|
pip install pwntools
|
However, some of the features (ROP generation and assembling/disassembling foreign architectures) require non-Python dependencies. For more information, see the complete installation instructions here.
