Summary

Add two new MessageDigest algorithms -- SHAKE128-256 and SHAKE256-512 -- to the SUN security provider.

Problem

SHAKE128-256 and SHAKE256-512 are used in many new high-level algorithms, including CMS for EdDSA, new signature algorithms, and HSS/LMS.

Solution

Add two new MessageDigest algorithms -- SHAKE128-256 and SHAKE256-512 -- to the SUN security provider.

Specification

In the MessageDigest Algorithms section of the Java Security Standard Algorithm Names documentation, add two new rows:

SHAKE128-256    SHAKE128-256 produces a 256 bit digest.
SHAKE256-512    SHAKE256-512 produces a 512 bit digest.

In The SUN Provider (a part of the Security Guide), add "SHAKE128-256" and "SHAKE256-512" to the "MessageDigest" row.
