Provided by: gnutls-doc_3.6.13-2ubuntu1.12_all bug

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
