int gnutls_x509_privkey_get_seed(gnutls_x509_privkey_t key, gnutls_digest_algorithm_t * digest, void * seed, size_t * seed_size);
- gnutls_x509_privkey_t key
should contain a gnutls_x509_privkey_t type
- gnutls_digest_algorithm_t * digest
if non-NULL it will contain the digest algorithm used for key generation (if applicable)
- void * seed
where seed will be copied to
- size_t * seed_size
originally holds the size of seed , will be updated with actual size
This function will return the seed that was used to generate the given private key. That function will succeed only if the key was generated as a provable key.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
