NAME

4     fido_dev_get_assert — obtains an assertion from a FIDO2 device
5

SYNOPSIS

7     #include <fido.h>
8
9     int
10     fido_dev_get_assert(fido_dev_t *dev, fido_assert_t *assert,
11         const char *pin);
12

DESCRIPTION

14     The fido_dev_get_assert() function asks the FIDO2 device represented by
15     dev for an assertion according to the following parameters defined in
16     assert:
17
18     -   relying party ID;
19     -   client data hash;
20     -   list of allowed credential IDs;
21     -   user presence and user verification attributes.
22
23     See fido_assert_set_authdata(3) for information on how these values are
24     set.
25
26     If a PIN is not needed to authenticate the request against dev, then pin
27     may be NULL.  Otherwise pin must point to a NUL-terminated UTF-8 string.
28
29     After a successful call to fido_dev_get_assert(), the
30     fido_assert_count(3), fido_assert_user_display_name(3),
31     fido_assert_user_icon(3), fido_assert_user_name(3),
32     fido_assert_authdata_ptr(3), fido_assert_user_id_ptr(3),
33     fido_assert_sig_ptr(3), and fido_assert_sigcount(3) functions may be in‐
34     voked on assert to retrieve the various attributes of the generated as‐
35     sertion.
36
37     Please note that fido_dev_get_assert() is synchronous and will block if
38     necessary.
