int gnutls_openpgp_privkey_get_subkey_fingerprint(gnutls_openpgp_privkey_t key, unsigned int idx, void * fpr, size_t * fprlen);

gnutls_openpgp_privkey_t key

the raw data that contains the OpenPGP secret key.

unsigned int idx

the subkey index

void * fpr

the buffer to save the fingerprint, must hold at least 20 bytes.

size_t * fprlen

the integer to save the length of the fingerprint.

Get the fingerprint of an OpenPGP subkey. Depends on the algorithm, the fingerprint can be 16 or 20 bytes.

On success, 0 is returned, or an error code.
