This is the first generation of the Codec used by Motion-Twin to encrypt client<>server exchanges in their games.

Note
If you are looking for how to use it, you can look at some examples in the unit tests.

new Codec(key: String)

// The key used for encoding and decoding a string.
private key: Array

// return the encoded or decoded `text` string based on `key`.
public run(text: String): String
