-/**
-   This is the Service Provider Interface (SPI) for MessageDigest
-   class in java.security. It provides the back end functionality
-   for the MessageDigest class so that it can compute message
-   hashes. The default hashes are SHA-1 and MD5. A message hash
-   takes data of arbitrary length and produces a unique number
-   representing it.
-
-   Cryptography service providers who want to implement their
-   own message digest hashes need only to subclass this class.
-
-   The implementation of a Cloneable interface is left to up to
-   the programmer of a subclass.
