You could use the ruby openssl standard library.

In my latest project I needed to encrypt cc numbers. I based my code  
on this blog  
[http://blog.leetsoft.com/2006/03/14/simple-encryption](http://blog.leetsoft.com/2006/03/14/simple-encryption)

Nothing needed except the standard ruby library.

I struggled with this a couple weeks ago for saving Social Security  
Numbers and Salaries in the DB encrypted. Not sure how secure this is,  
but this is perhaps a start:
