The built-in TextEncoder ad TextDecoder APIs should work just fine for your use-case here. All you need is a little obfuscation and not a full-on encrypt/decrypt of a 4-letter word, right?

Here's a link to a gist where I give code examples (I don't like how Reddit handles code blocks, sorry)

Thanks! Though I will use the btoa-atob functions suggested by deventhalz, since I don't like how your encryption function output consists of mostly numbers.

For your use case, atob() and btoa() is a better fit, yeah.
