fido_assert_allow_cred,
fido_assert_empty_allow_list —
manage allow lists in a FIDO2 assertion
#include
<fido.h>
int
fido_assert_allow_cred(fido_assert_t
*assert, const unsigned
char *ptr, size_t
len);
int
fido_assert_empty_allow_list(fido_assert_t
*assert);
The
fido_assert_allow_cred()
function adds ptr to the list of credentials allowed
in assert, 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_assert_allow_cred() fails, the
existing list of allowed credentials is preserved.
For the format of a FIDO2 credential ID, please refer to the Web Authentication (webauthn) standard.
The
fido_assert_empty_allow_list()
function empties the list of credentials allowed in
assert.
The error codes returned by
fido_assert_allow_cred() and
fido_assert_empty_allow_list() are defined in
<fido/err.h>. On success,
FIDO_OK is returned.
