NAME
gnutls_x509_privkey_generate - API function
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_privkey_generate(gnutls_x509_privkey_t key,
gnutls_pk_algorithm_t algo, unsigned int bits, unsigned int flags);
ARGUMENTS
gnutls_x509_privkey_t key
an initialized 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.
DESCRIPTION
This function will generate a random private key. Note that this func-
tion 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_x509_privkey_generate2() for more information.
Note that when generating an elliptic curve key, the curve can be sub-
stituted 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_generate(), gnutls_x509_privkey_generate2().
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er-
ror value.
