Note that the failure code part has been added to better diagnose
problems if a wrong gpg version is used.  If verything works right we
should not get this because we check that the gnupg version sis either
>= 2.4.4 or less than 2.3 and >= 2.2.42.

Note further that the v5fpr field may also be used to get the SHA-256
fingerprint of X.509 certificates (even without passing the new mode
flag).
