  27. *
  28. * The Message Digest (MD) or Hashing module provides one-way hashing
  29. * functions. Such functions can be used for creating a hash message
  30. * authentication code (HMAC) when sending a message. Such a HMAC can be used
  31. * in combination with a private key for authentication, which is a message
  32. * integrity control.
  33. *
  34. * All hash algorithms can be accessed via the generic MD layer (see
  35. * \c mbedtls_md_setup())
  36. *
  37. * The following hashing-algorithms are provided:
  38. * - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest.
  39. * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by
  40. * NIST and NSA.
  41. *
  42. * This module provides one-way hashing which can be used for authentication.
