gnutls_decode_rs_value - API function
#include <gnutls/crypto.h>
int gnutls_decode_rs_value(const gnutls_datum_t * sig_value,
gnutls_datum_t * r, gnutls_datum_t * s);
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
This function will decode the provided sig_value , into r and
s elements. 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 being interpreted as negative values. The value should be
deallocated using gnutls_free().
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error
code is returned.
