#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.
