Function silc_hmac_init SYNOPSIS
        void silc_hmac_init(SilcHmac hmac);
DESCRIPTION
        Sometimes calling the silc_hmac_make might not be the most
        optimal case of doing MACs.  If you have a lot of different data
        that you need to put together for computing a MAC you may either
        put them into a buffer and compute the MAC from the buffer by
        calling the silc_hmac_make, or you can use the silc_hmac_init,
        silc_hmac_update and silc_hmac_final to do the MAC.  This function
        prepares the allocated HMAC context for this kind of MAC
        computation.  The caller must have been called the function
        silc_hmac_set_key before calling this function.  To add the
        data to be used in the MAC computation call the silc_hmac_update
        function.
