NAME
       gnutls_x509_privkey_get_key_id - Return unique ID of the key's parameters

SYNOPSIS
       #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);

ARGUMENTS
       gnutls_x509_privkey_t key
		   Holds the key

       unsigned int flags
		   should be 0 for now

       unsigned char * output_data
		   will contain the key ID

       size_t * output_data_size
		   holds the size of output_data (and will be replaced by the actual size of parameters)

DESCRIPTION
       This  function will return a unique ID the depends on the public key parameters. This ID can be used in checking whether a certificate cor-
       responds 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.

RETURNS
       On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.
