Синопсис (Synopsis)
#include <gnutls/abstract.h>
int gnutls_pubkey_get_key_id(gnutls_pubkey_t key, unsigned int
flags, unsigned char * output_data, size_t * output_data_size);
Аргументы (Arguments)
gnutls_pubkey_t key
Holds the public 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)
Описание (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 public 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.

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