minicrypto.lua : A tiny RC4 implementation in pure lua

Usage

• Encryption:

local ciphertext = minicrypto.encrypt(content, key)

• Decryption:

local content = minicrypto.decrypt(content, key)

Sanity Check

RC4 is not a secure cryptographic system see here. I'm not suggesting you use this for actual security.

I used this for a system where I wanted to further obscure data which was being transmitted over an already secure channel.

Installation

Simply download the .lua file. I've provided the global variable minicrypto to access the functions so I dont have to write an implemtation for the myriad of ways embedded lua contexts like to require their scripts.
