You need to take a look at the java.security classes (what used to tbe the JCE):

In there you'll find everything you need to do what you want (depending on which algorithm you need).

e.g. MessageDigest for MD5/SHA etc:

Check these against the Google App Engine whitelist here, I'm not sure what's supported and what isn't.

The java.security stuff can be a bit of a pain to work with sometimes, you may alternatively want to use Jasypt - which is a more simplified API that works with any JCE:
