Api function
#include <gnutls/x509.h>
int gnutls_x509_privkey_get_key_id(gnutls_x509_privkey_t key, unsigned int flags, unsigned char * output_data, size_t * output_data_size);
Holds the key
should be 0 for now
will contain the key ID
holds the size of output_data (and will be replaced by the actual size of parameters)
This function will return a unique ID that depends on the public key parameters. This ID can be used in checking whether a certificate corresponds to the given key.
If the buffer provided is not long enough to hold the output, then * output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned. The output will normally be a SHA-1 hash output, which is 20 bytes.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
