@deftypefun {int} {gnutls_privkey_import_ext2} (gnutls_privkey_t @var{pkey}, gnutls_pk_algorithm_t @var{pk}, void * @var{userdata}, gnutls_privkey_sign_func @var{sign_func}, gnutls_privkey_decrypt_func @var{decrypt_func}, gnutls_privkey_deinit_func @var{deinit_func}, unsigned int @var{flags})
@var{pkey}: The private key
@var{pk}: The public key algorithm
@var{userdata}: private data to be provided to the callbacks
@var{sign_func}: callback for signature operations
@var{decrypt_func}: callback for decryption operations
@var{deinit_func}: a deinitialization function
@var{flags}: Flags for the import
This function will associate the given callbacks with the
@code{gnutls_privkey_t} structure. At least one of the two callbacks
must be non-null. If a deinitialization function is provided
then flags is assumed to contain @code{GNUTLS_PRIVKEY_IMPORT_AUTO_RELEASE} .
Note that the signing function is supposed to "raw" sign data, i.e.,
without any hashing or preprocessing. In case of RSA the DigestInfo
will be provided, and the signing function is expected to do the PKCS @code{1}
1.5 padding and the exponentiation.
@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS} (0) is returned, otherwise a
negative error value.
@strong{Since:} 3.1
