All Implemented Interfaces:

TaggedIF, XdrAble

Direct Known Subclasses:

MD2Digest, MD5Digest, SHA1Digest, SHA256Digest, SHA384Digest, SHA512Digest

public abstract class Digest
extends Tagged

Represents the results of a cryptographic hash algorithm applied to the serialization (using XDR) of a Tagged object. For verification purposes, the algorithm used is encoded in the tag type.
