NAME         top

       gnutls_x509_privkey_generate - API function

SYNOPSIS         top

       #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         top

       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         top

       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_x509_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_generate(),
       gnutls_x509_privkey_generate2().

RETURNS         top

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