gnutls_privkey_import_ext — API function


#include <gnutls/abstract.h>

int gnutls_privkey_import_ext(gnutls_privkey_t pkey, gnutls_pk_algorithm_t pk, void * userdata, gnutls_privkey_sign_func sign_func, gnutls_privkey_decrypt_func decrypt_func, unsigned int flags);


gnutls_privkey_t pkey
The private key
gnutls_pk_algorithm_t pk
The public key algorithm
void * userdata
private data to be provided to the callbacks
gnutls_privkey_sign_func sign_func
callback for signature operations
gnutls_privkey_decrypt_func decrypt_func
callback for decryption operations
unsigned int flags
Flags for the import


This function will associate the given callbacks with the gnutls_privkey_t type. At least one of the two callbacks must be non-null.

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.

See also gnutls_privkey_import_ext3().


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