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);
