gnutls_encode_gost_rs_value − API function
#include <gnutls/crypto.h>
int gnutls_encode_gost_rs_value(gnutls_datum_t * sig_value, const gnutls_datum_t * r, const gnutls_datum_t * s);
gnutls_datum_t * sig_value
will hold a GOST signature according to RFC 4491 section 2.2.2
const gnutls_datum_t * r
must contain the r value
const gnutls_datum_t * s
must contain the s value
This function will encode the provided r and s values, into binary representation according to RFC 4491 section 2.2.2, used for GOST R 34.10−2001 (and thus also for GOST R 34.10−2012) signatures.
The output value should be deallocated using gnutls_free().
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
