- * @addtogroup hashing_module Hashing module
- *
- * The Message Digest (MD) or 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 mbedtls_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.
