Detailed Description
Computes the SHA512 hash from a byte stream.
This class is a rewrite in C++ of the sha512 hash computing algorithm present in the Libgcrypt. Please see the GNU Privacy Guard project website for more informations.
This abstract class implements the SHA384 hash and SHA512 hash computing.
