Simon Butcher00aea9a2016-03-17 00:30:35 +000026 * The Message Digest (MD) or Hashing module provides one-way hashing
27 * functions. Such functions can be used for creating a hash message
28 * authentication code (HMAC) when sending a message. Such a HMAC can be used
29 * in combination with a private key for authentication, which is a message
30 * integrity control.
Paul Bakkerdcbfdcc2013-09-10 16:16:50 +020031 *
32 * All hash algorithms can be accessed via the generic MD layer (see
Simon Butcher00aea9a2016-03-17 00:30:35 +000033 * \c mbedtls_md_setup())
Paul Bakkerdcbfdcc2013-09-10 16:16:50 +020034 *
Paul Bakker37ca75d2011-01-06 12:28:03 +000035 * The following hashing-algorithms are provided:
Manuel Pégourié-Gonnardd4b91732015-03-25 16:25:23 +010036 * - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest.
Paul Bakkerdcbfdcc2013-09-10 16:16:50 +020037 * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by
Manuel Pégourié-Gonnardd4b91732015-03-25 16:25:23 +010038 * NIST and NSA.
Paul Bakker37ca75d2011-01-06 12:28:03 +000039 *
40 * This module provides one-way hashing which can be used for authentication.
