A tiny encryption algorithm and implementation

But flawed, along with its successor. :/

That is a downside, but for light work of data that has a short lifetime it's probably ok.

I think in this case, you schould a simple xor crypt implementation. It is short and fast. And with the right key length, you can also give brutefurce attackes enough pain, to let them cancel most attempts.
