Function silc_hash_update
SYNOPSIS

        void silc_hash_update(SilcHash hash, const unsigned char *data,
                              SilcUInt32 data_len);

DESCRIPTION

        This function may be called to add data to be used in the digest
        computation.  This can be called multiple times to add data from
        many sources before actually computing the digest.  Once you've
        added all the data you need you can call the silc_hash_final to
        actually produce the message digest value.

EXAMPLE

        unsigned char digest[20];

        silc_hash_init(hash);
        silc_hash_update(hash, data, data_len);
        silc_hash_update(hash, more_data, more_data_len);
        silc_hash_final(hash, digest);
