gnutls_privkey_generate - API function
#include <gnutls/abstract.h> int gnutls_privkey_generate(gnutls_privkey_t pkey, gnutls_pk_algorithm_t algo, unsigned int bits, unsigned int flags);
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.
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().
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
