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. 31 * 32 * All hash algorithms can be accessed via the generic MD layer (see 33 * \c mbedtls_md_setup()) 34 * 35 * The following hashing-algorithms are provided: 36 * - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest. 37 * - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by 38 * NIST and NSA. 39 * 40 * This module provides one-way hashing which can be used for authentication. 41 */ 42
