What it is

A CLI tool & 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!

Most of the methods are available as commands CLI tool:

$ ctf-party 'security' to_hex
7365637572697479

$ ctf-party 'NzQ2Zjc0NmY=' from_b64 hex2str str2bin
01110100011011110111010001101111
