| * @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. |
