Hi list.

I need to encode some data with a userID and then also be able to
decode it with the same key.

This is basically a quick approach to obfuscate URLs. Its for an
environment where we know the users ID with some degree of certainty.

Are there any libraries/simple algorithms to do this in ruby? it might
be as simple as bitshiting a string around...

any other suggested alternatives to this approach?
