encryption class?

[Anon]

Hi

I need to be able to do some kind of 2 way encryption to store secure info on a site. My host does not have mcrypt setup. Can someone point out some kind of class/thingy that I can use to do this that will not require me to install modules?

Thanks a bunch

This might do the trick, never used it myself:
