gnutls_privkey_generate2 — API function


#include <gnutls/abstract.h>

int gnutls_privkey_generate2(gnutls_privkey_t pkey, gnutls_pk_algorithm_t algo, unsigned int bits, unsigned int flags, const gnutls_keygen_data_st * data, unsigned data_size);


gnutls_privkey_t pkey
The private key
gnutls_pk_algorithm_t algo
is one of the algorithms in gnutls_pk_algorithm_t.
unsigned int bits
the size of the modulus
unsigned int flags
Must be zero or flags from gnutls_privkey_flags_t.
const gnutls_keygen_data_st * data
Allow specifying gnutls_keygen_data_st types such as the seed to be used.
unsigned data_size
The number of data available.


This function will generate a random private key. Note that this function must be called on an empty private key. The flag GNUTLS_PRIVKEY_FLAG_PROVABLE instructs the key generation process to use algorithms like Shawe-Taylor which generate provable parameters out of a seed.

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.

Do not set the number of bits directly, use gnutls_sec_param_to_pk_bits().


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