NAME
gnutls_x509_privkey_get_key_id - API function
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
a key
unsigned int flags
should be one of the flags from gnutls_keyid_flags_t
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 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.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error value.
