|  | * @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_setup()) | 
|  | * | 
|  | * 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. |
