36 * @brief This class implements the MD5 HMAC algorithm.
40 * The %Md5Hmac class implements the basic hash procedure to encrypt messages using the Hash Message Authentication Code (HMAC) algorithm, which provides a hash with a secret key. @n
42 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/security/hashing.htm">Hashing</a>.
