gnutls_decode_gost_rs_value - API function
#include <gnutls/crypto.h> int gnutls_decode_gost_rs_value(const gnutls_datum_t * sig_value, gnutls_datum_t * r, gnutls_datum_t * s);
const gnutls_datum_t * sig_value will holds a GOST signature according to RFC 4491 section 2.2.2 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. See RFC 4491 section 2.2.2 for the format of signature value. 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.
