# [SYNOPSIS](#SYNOPSIS)

**#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);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_datum\_t * sig\_value](#gnutls_datum_t)

[const gnutls\_datum\_t * s](#const~2)

must contain the s value

# [DESCRIPTION](#DESCRIPTION)

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()**.
