Subject: How to send a secure email (maybe PGP)?

Hello,

In an application I have to send an email containing a Credit Card
number, but I don't know how to secure it!!!

Is there a ruby library or best practice for securing an email
content, I googled for it with no success.

Thanks in advance,
- Dunnil
