/**
 * @addtogroup hashing_module Hashing module
 *
 * The Hashing module provides one-way hashing functions. Such functions can be
 * used for creating a hash message authentication code (HMAC) when sending a
 * message. Such a HMAC can be used in combination with a private key
 * for authentication, which is a message integrity control.
 *
 * All hash algorithms can be accessed via the generic MD layer (see
 * \c md_init_ctx())
 *
 * The following hashing-algorithms are provided:
 * - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest.
 * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by
 *   NIST and NSA.
 *
 * This module provides one-way hashing which can be used for authentication.
