ctf-party

What it is

A library to enhance and speed up script/exploit writing for CTF players (or security researchers, bug bounty hunters, pentesters but mostly focused on CTF) by patching the String class to add a short syntax of usual code patterns. The philosophy is also to keep the library to be pure ruby (no dependencies) and not to re-implement what another library is already doing well (eg. xorcist for xor).

For example instead of writing:

require 'base64'

myvar = 'string'
myvar = Base64.strict_encode64(myvar)

Just write (shorter and easier to remember):

require 'ctf_party'

myvar = 'string'
myvar.to_b64!

Features

• base64: to_b64, to_b64!, from_b64, from_b64!, b64?
• digest: md5, md5!, sha1, sha1!, etc.
• flag: flag, flag!, flag? (apply/check a flag format)
• rot: rot, rot!, rot13, rot13!
