NAME

       gnutls_certificate_get_x509_key - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int  gnutls_certificate_get_x509_key(gnutls_certificate_credentials_t res, unsigned index,
       gnutls_x509_privkey_t * key);

ARGUMENTS

       gnutls_certificate_credentials_t res
                   is a gnutls_certificate_credentials_t type.

       unsigned index
                   The index of the key to obtain.

       gnutls_x509_privkey_t * key
                   Location to store the key.

DESCRIPTION

       Obtains  a  X.509  private  key   that   has   been   stored   in    res   with   one   of
       gnutls_certificate_set_x509_key(),                           gnutls_certificate_set_key(),
       gnutls_certificate_set_x509_key_file(),           gnutls_certificate_set_x509_key_file2(),
       gnutls_certificate_set_x509_key_mem(),   or   gnutls_certificate_set_x509_key_mem2().  The
       returned key must be deallocated with gnutls_x509_privkey_deinit() when no longer needed.

       The  index matches the  return  value  of  gnutls_certificate_set_x509_key()  and  friends
       functions, when the GNUTLS_CERTIFICATE_API_V2 flag is set.

       If  there  is  no  key  with  the  given  index,  GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is
       returned. If the key with the given index is not a X.509 key, GNUTLS_E_INVALID_REQUEST  is
       returned.

RETURNS

       GNUTLS_E_SUCCESS (0) on success, or a negative error code.

SINCE

       3.4.0
