@deftypefun {int} {gnutls_pubkey_encrypt_data} (gnutls_pubkey_t @var{key}, unsigned int @var{flags}, const gnutls_datum_t * @var{plaintext}, gnutls_datum_t * @var{ciphertext})
@var{key}: Holds the public key

@var{flags}: should be 0 for now

@var{plaintext}: The data to be encrypted

@var{ciphertext}: contains the encrypted data

This function will encrypt the given data, using the public
key. On success the  @code{ciphertext} will be allocated using @code{gnutls_malloc()} .

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.

@strong{Since:} 3.0
