@deftypefun {int} {gnutls_pubkey_import} (gnutls_pubkey_t @var{key}, const gnutls_datum_t * @var{data}, gnutls_x509_crt_fmt_t @var{format})
@var{key}: The public key.
@var{data}: The DER or PEM encoded certificate.
@var{format}: One of DER or PEM
This function will import the provided public key in

of "PUBLIC KEY".
