const gnutls_datum_t * sig_value
holds a Dss-Sig-Value DER or BER encoded structure
gnutls_datum_t * r
will contain the r value
gnutls_datum_t * s
will contain the s value
DESCRIPTION
This function will decode the provided sig_value , into r and s ele-
ments. The Dss-Sig-Value is used for DSA and ECDSA signatures.
The output values may be padded with a zero byte to prevent them from
