fido_dev_get_assert —
obtains an assertion from a FIDO2 device
#include
<fido.h>
int
fido_dev_get_assert(fido_dev_t
*dev, fido_assert_t
*assert, const char
*pin);
The
fido_dev_get_assert()
function asks the FIDO2 device represented by dev for
an assertion according to the following parameters defined in
assert:
relying party ID;client data hash;list of allowed credential IDs;user presence and user verification
attributes.See fido_assert_set_authdata(3) for information on how these values are set.
If a PIN is not needed to authenticate the request against dev, then pin may be NULL. Otherwise pin must point to a NUL-terminated UTF-8 string.
After a successful call to
fido_dev_get_assert(),
the fido_assert_count(3),
fido_assert_user_display_name(3),
fido_assert_user_icon(3),
fido_assert_user_name(3),
fido_assert_authdata_ptr(3),
fido_assert_user_id_ptr(3),
fido_assert_sig_ptr(3),
and
fido_assert_sigcount(3)
functions may be invoked on assert to retrieve the
various attributes of the generated assertion.
Please note that
fido_dev_get_assert()
is synchronous and will block if necessary.
The error codes returned by
fido_dev_get_assert() are defined in
<fido/err.h>. On success,
FIDO_OK is returned.
