This is the patch as discussed on [1].

Originally I wanted to provide another context property to specify the MessageDigest Provider. So I've checked how the other properties are set and saw that the key strings a scattered through the code. As a user I would prefer to use a constant, maybe having some attached javadoc to it, therefore I've moved the strings to constants in the appropriated classes [2]

As MessageDigests are used also in other places, I've checked their creation and found the JceMapper class. So the patch centralized the MD creation in MessageDigestAlgorithm and now user code can overwrite the provider over JceMapper.setProviderID.

Andi.
