gnutls_pubkey_export_ecc_raw — API function


#include <gnutls/abstract.h>

int gnutls_pubkey_export_ecc_raw(gnutls_pubkey_t key, gnutls_ecc_curve_t * curve, gnutls_datum_t * x, gnutls_datum_t * y);


gnutls_pubkey_t key

Holds the public key

gnutls_ecc_curve_t * curve

will hold the curve (may be NULL)

gnutls_datum_t * x

will hold x-coordinate (may be NULL)

gnutls_datum_t * y

will hold y-coordinate (may be NULL)


This function will export the ECC public key's parameters found in the given key.  The new parameters will be allocated using gnutls_malloc() and will be stored in the appropriate datum.

In EdDSA curves the  y parameter will be NULL and the other parameters will be in the native format for the curve.

This function allows for NULL parameters since 3.4.1.


GNUTLS_E_SUCCESS on success, otherwise a negative error code.
