NAME         top

       gnutls_x509_privkey_generate2 - API function

SYNOPSIS         top

       #include <gnutls/x509.h>

       int gnutls_x509_privkey_generate2(gnutls_x509_privkey_t key,
       gnutls_pk_algorithm_t algo, unsigned int bits, unsigned int flags,
       const gnutls_keygen_data_st * data, unsigned data_size);

ARGUMENTS         top

       gnutls_x509_privkey_t key
                   a 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.

DESCRIPTION         top

       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 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.

       For DSA keys, if the subgroup size needs to be specified check the
       GNUTLS_SUBGROUP_TO_BITS() macro.

       When generating RSA-PSS keys which should require specific
       parameters, you should use  data of type GNUTLS_KEYGEN_SPKI to
       specify the SubjectPublicKeyInfo parameters.

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

RETURNS         top

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