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](https://github.com/fny/xorcist) for xor).

For example instead of writing:

```auto
require 'base64'myvar = 'string'myvar = Base64.strict_encode64(myvar)

```

Just write (shorter and easier to remember):

```auto
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!`
- hex: `hex2dec`, `dec2hex`, `to_hex`, `from_hex`, `hex2bin`, `bin2hex` and bang versions
