FIDO_DEV_GET_ASSERT(3) FreeBSD Library Functions Manual NAME fido_dev_get_assert - obtains an assertion from a FIDO2 device SYNOPSIS #include <fido.h> int fido_dev_get_assert(fido_dev_t *dev, fido_assert_t *assert, const char *pin); DESCRIPTION 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. RETURN VALUES The error codes returned by fido_dev_get_assert() are defined in <fido/err.h>. On success, FIDO_OK is returned. SEE ALSO fido_assert_new(3), fido_assert_set_authdata(3) FreeBSD 14.1-RELEASE-p8 August 29, 2022 FreeBSD 14.1-RELEASE-p8
