Description

I've slightly modified the DigestUtils class:

• changed the visibility (protected --> public) of a few methods: these methods are generally useful if one just wants to get a MessageDigest instance for a given algorithm
• added two 'updateDigest' methods which can be used to add more data to digest to the provided MessageDigest. The advantage for the one that accepts a String argument is that it keeps the same logic as the rest of DigestUtils (uses getBytesUtf8). The second one which accepts a byte array is there for consistency
