Detailed Description

This class represents the implementation of the SHA384 and SHA512 algorithm.

Basically the class provides six public member-functions to create a hash: SHA384_Init(), SHA384_Update(), SHA384_End(), SHA512_Init(), SHA512_Update() and SHA512_End(). If you want to create a hash based on a string or file quickly you should use the sha384wrapper or sha512wrapper classes.
