fido_cred_exclude,
fido_cred_empty_exclude_list —
manage exclude lists in a FIDO2 credential
#include
<fido.h>
int
fido_cred_exclude(fido_cred_t
*cred, const unsigned
char *ptr, size_t
len);
int
fido_cred_empty_exclude_list(fido_cred_t
*cred);
The
fido_cred_exclude()
function adds ptr to the list of credentials excluded
by cred, where ptr points to a
credential ID of len bytes. A copy of
ptr is made, and no references to the passed pointer
are kept. If fido_cred_exclude() fails, the existing
list of excluded credentials is preserved.
If fido_cred_exclude returns success and
cred is later passed to
fido_dev_make_cred(3) on a
device that contains the credential denoted by ptr,
then fido_dev_make_cred(3)
will fail.
For the format of a FIDO2 credential ID, please refer to the Web Authentication (webauthn) standard.
The
fido_cred_empty_exclude_list()
function empties the list of credentials excluded by
cred.
The error codes returned by
fido_cred_exclude() and
fido_cred_empty_exclude_list() are defined in
<fido/err.h>. On success,
FIDO_OK is returned.
