fido_assert_allow_cred - Man Page

#include <fido.h>

int
fido_assert_allow_cred(fido_assert_t *assert, const unsigned char *ptr, size_t len);

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 FIDO 2 credential ID, please refer to the Web Authentication (webauthn) standard.

The error codes returned by fido_assert_allow_cred() are defined in <fido/err.h>. On success, FIDO_OK is returned.
