NAME
       gnutls_decode_rs_value - API function


SYNOPSIS
       #include <gnutls/crypto.h>

       int   gnutls_decode_rs_value(const   gnutls_datum_t   *  sig_value,  gnutls_datum_t  *  r,
       gnutls_datum_t * s);


ARGUMENTS
       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


DESCRIPTION
       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().


RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.


SINCE
       3.6.0
