Class SHA3

java.lang.Object

java.security.MessageDigestSpi

java.security.MessageDigest

com.safenetinc.luna.provider.digest.SHA3

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

SHA3.SHA3_224, SHA3.SHA3_256, SHA3.SHA3_384, SHA3.SHA3_512

public class SHA3
extends java.security.MessageDigest

This class implements the Secure Hash Algorithm SHA-3 developed by the National Institute of Standards and Technology along with the National Security Agency as defined in FIPS PUB 202.

It implements java.security.MessageDigestSpi, and can be used through Java Cryptography Architecture (JCA), as a pluggable MessageDigest implementation.
