public class Sha512Crypt
extends Object

This class defines a method, Sha512_crypt(), which takes a password and a salt string and generates a Sha512 encrypted password entry. This class implements the new generation, scalable, SHA512-based Unix 'crypt' algorithm developed by a group of engineers from Red Hat, Sun, IBM, and HP for common use in the Unix and Linux /etc/shadow files. The Linux glibc library (starting at version 2.7) includes support for validating passwords hashed using this algorithm. The algorithm itself was released into the Public Domain by Ulrich Drepper <drepper@redhat.com>. A discussion of the rationale and development of this algorithm is at http://people.redhat.com/drepper/sha-crypt.html and the specification and a sample C language implementation is at http://people.redhat.com/drepper/SHA-crypt.txt
