> MessageDigest.getInstance("SomeAlg") throws NoSuchAlgorithm exception (a checked exception).  This is annoying as it causes everyone that uses standard algs like MD5 to surround their code in try/catch.  We should concentrate the creation in one method that doesn't raise an exception (i.e. catches NoSuchAlgorithm and raises a RuntimeException) just to clean the code up a little.
