It is much easier to just use the java.security.MessageDigest class included with the JDK.
If you do want to use JSS, the best way to do it is to use the JCA API with JSS as the implementation provider. Some examples of this can be found in: http://lxr.mozilla.org/mozilla/source/security/jss/org/mozilla/jss/tests/DigestTest.java This program does some other things you don't need to do. The most important things you need to do are: 1. Initialize CryptoManager (line 59) 2. Get a MessageDigest instance with the JSS provider ( line 70) 3. Call digest() on the MessageDigest object.
