WIP: pwntools on Ruby!

pwntools-ruby

Always sad when playing CTF that there's nothing equivalent to pwntools in Python. While pwntools is awesome, I always love Ruby far more than Python... So this is an attempt to create such library.

There's almost NOTHING here now. (Edit: there's something here now, but not much 😉) Going to implement important things (socket, tubes, asm/disasm, pack/unpack utilities) first. Would try to have consistent naming with original pwntools, and do things in Ruby style.

Example Usage

# encoding: ASCII-8BIT
# The encoding line is important most time, or you'll get "\u0000" when using "\x00" in code,
# which is NOT what we want when doing pwn...

require 'pwn'

p pack(0x41424344)  # 'DCBA'
context.endian = 'big'
p pack(0x41424344)  # 'ABCD'

context.local(bits: 16) do
  p pack(0x4142)  # 'AB'
end

Development

git clone [email protected]:peter50216/pwntools-ruby.git
cd pwntools-ruby
rake

Note to irb users

irb defines main.context.

For the ease of exploit development in irb, that method would be removed if you use require 'pwn'.

You can still get the IRB::Context by irb_context.
