NAME

     fido_assert_allow_cred, fido_assert_empty_allow_list — manage allow lists in a FIDO2 assertion

SYNOPSIS

     #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);

DESCRIPTION

     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.

RETURN VALUES

     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.
