NAME         top

       gnutls_privkey_import_ext3 - API function

SYNOPSIS         top

       #include <gnutls/abstract.h>

       int gnutls_privkey_import_ext3(gnutls_privkey_t pkey, void *
       userdata, gnutls_privkey_sign_func sign_fn,
       gnutls_privkey_decrypt_func decrypt_fn,
       gnutls_privkey_deinit_func deinit_fn, gnutls_privkey_info_func
       info_fn, unsigned int flags);

ARGUMENTS         top

       gnutls_privkey_t pkey
                   The private key

       void * userdata
                   private data to be provided to the callbacks

       gnutls_privkey_sign_func sign_fn
                   callback for signature operations

       gnutls_privkey_decrypt_func decrypt_fn
                   callback for decryption operations

       gnutls_privkey_deinit_func deinit_fn
                   a deinitialization function

       gnutls_privkey_info_func info_fn
                   returns info about the public key algorithm (should
                   not be NULL)

       unsigned int flags
                   Flags for the import

DESCRIPTION         top

       This function will associate the given callbacks with the
       gnutls_privkey_t type. At least one of the two callbacks must be
       non-null. If a deinitialization function is provided then flags
       is assumed to contain 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 1 1.5 padding and the exponentiation.

       The  info_fn must provide information on the algorithms supported
       by this private key, and should support the flags
       must return -1 on unknown flags.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
       negative error value.
