You can take a look at the Crypt libraries in PEAR.  I've used the HCE_MD5
library for exactly what you're looking for.  This allows you to encrypt
the data with a password.

However, that requires the data be fed through a script on the recipients
computer to decode it.

If that is a problem, the better option for you might be use PGP to encrypt
it for the recipient.  Many mail programs support PGP to automagically
decrypt an email upon receipt, given the users passphrase for their private
