Use the JCE (Java Cryptographic Extension), available from Sun (<http://java.sun.com/products/jce/>). Remember that after encryption, you will get binary output, so don't forget to base64 encode, otherwise X.25 mailing systems may corrupt the mailed data. I think there are some export restrictions on this though. Or use an S/MIME provider to work with JavaMail. This would include support for email signing and encryption. The Phaos S/MIME toolkit <http://www.phaos.com/e_security/prod_smime.html> and JCSI <http://security.dstc.edu.au/projects/java/release2.html> are two implementations you can look into.
