29 * The Message Digest (MD) or Hashing module provides one-way hashing
30 * functions. Such functions can be used for creating a hash message
31 * authentication code (HMAC) when sending a message. Such a HMAC can be used
32 * in combination with a private key for authentication, which is a message
35 * All hash algorithms can be accessed via the generic MD layer (see
36 * \c mbedtls_md_setup())
38 * The following hashing-algorithms are provided:
39 * - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest.
40 * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by
43 * This module provides one-way hashing which can be used for authentication.
