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 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.

RETURN VALUE

In case of failure a negative value will be returned, and 0 on success.
