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. 30 */
