Provided by: gnutls-doc_3.5.18-1ubuntu1.6_all bug

NAME
       gnutls_privkey_import_ext3 - API function


SYNOPSIS
       #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
       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
       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 GNUTLS_PRIVKEY_INFO_PK_ALGO and GNUTLS_PRIVKEY_INFO_SIGN_ALGO. It must  return  -1  on  unknown
       flags.


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


SINCE
       3.4.0
