+ * The function takes a pointer to the current hash values, a pointer to the

+ * The function only processes complete blocks, there is no functionality to
+ * store partial blocks.  All message padding and hash value initialization must
+ * be done outside the update function.

+ * The indented lines in the loop are instructions related to rounds processing.
