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 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.  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 .

RETURNS

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