Compress/obfuscate URL to use in rewrite?

I need to add the URL of a 3rd-party website to a url, but I'd like to compress/obfuscate the host part. Are there any algorithms I can use which will hash the url, but also allow un-hashing?

For example; the url is http://www.twitter.com/myusername. What I'm serving currently (as a html link) is http://mysite.net/bounce/www.twitter.com/username. What I'd like to serve is something like http://mysite.net/bounce/X5nsSkdWfA/username, and have the bounce script decode |^/bounce/(.*)/| back to www.twitter.com.

I'd like to do this without storing the hash anywhere.

Suggestions?

You can use, for instance, ROT13 for obfuscating ;-)

$ echo twitter.com | rot13
gjvggre.pbz

Then you can use base64

$ echo twitter.com | base64

Naturally, they don't compress. You can come with something yourself for squeezing a few bits out of it.
