Функции API (API function)

Имя (Name)

gnutls_privkey_generate - API function


Синопсис (Synopsis)

#include <gnutls/abstract.h>

int gnutls_privkey_generate(gnutls_privkey_t pkey, gnutls_pk_algorithm_t algo, unsigned int bits, unsigned int flags);


Аргументы (Arguments)

gnutls_privkey_t pkey An initialized private key

gnutls_pk_algorithm_t algo is one of the algorithms in gnutls_pk_algorithm_t.

unsigned int bits the size of the parameters to generate

unsigned int flags Must be zero or flags from gnutls_privkey_flags_t.


Описание (Description)

This function will generate a random private key. Note that this function must be called on an initialized private key.

The flag GNUTLS_PRIVKEY_FLAG_PROVABLE instructs the key generation process to use algorithms like Shawe-Taylor (from FIPS PUB186-4) which generate provable parameters out of a seed for RSA and DSA keys. See gnutls_privkey_generate2() for more information.

Note that when generating an elliptic curve key, the curve can be substituted in the place of the bits parameter using the GNUTLS_CURVE_TO_BITS() macro. The input to the macro is any curve from gnutls_ecc_curve_t.

For DSA keys, if the subgroup size needs to be specified check the GNUTLS_SUBGROUP_TO_BITS() macro.

It is recommended to do not set the number of bits directly, use gnutls_sec_param_to_pk_bits() instead .

See also gnutls_privkey_generate2().


Возвращаемое значение (Return value)

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