14  *
15  * The Message Digest (MD) or Hashing module provides one-way hashing
16  * functions. Such functions can be used for creating a hash message
17  * authentication code (HMAC) when sending a message. Such a HMAC can be used
18  * in combination with a private key for authentication, which is a message
19  * integrity control.
20  *
21  * All hash algorithms can be accessed via the generic MD layer (see
22  * \c mbedtls_md_setup())
23  *
24  * The following hashing-algorithms are provided:
25  * - MD5 128-bit one-way hash function by Ron Rivest.
26  * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by
27  *   NIST and NSA.
28  *
29  * This module provides one-way hashing which can be used for authentication.
