/** * @file * Hashing module documentation file. */ /** * @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. * The following hashing-algorithms are provided: * - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest (see * \c md2_hmac(), \c md4_hmac() and \c md5_hmac()). * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by * NIST and NSA (see\c sha1_hmac(), \c sha2_hmac() and \c sha4_hmac()). * * This module provides one-way hashing which can be used for authentication. */
