gnutls_pubkey_get_openpgp_key_id — API function

Synopsis

#include <gnutls/abstract.h>

int gnutls_pubkey_get_openpgp_key_id(gnutls_pubkey_t key, unsigned int flags, unsigned char * output_data, size_t * output_data_size, unsigned int * subkey);

Arguments

gnutls_pubkey_t key
Holds the public key
unsigned int flags
should be 0 or GNUTLS_PUBKEY_GET_OPENPGP_FINGERPRINT
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)
unsigned int * subkey
Will be non zero if the key ID corresponds to a subkey

Description

This function returns the OpenPGP key ID of the corresponding key. The key is a unique ID that depends on the public key parameters.

If the flag GNUTLS_PUBKEY_GET_OPENPGP_FINGERPRINT is specified this function returns the fingerprint of the master 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 is GNUTLS_OPENPGP_KEYID_SIZE bytes long.

Returns

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