BSI (No not British Standard Institution, but
German Bundesamt fuer Sicherheit in der
Informationstechnik) list of certified
products.
Gpg4Win and Gpg4KDE are listed until 2022-06-30.
Thunderbird and Enigmail are not in list.
Enigmail will no longer be available for
Thunderbird 78, but you can copy message bodies between
Thunderbird and GPG using the clipboard. Of course, this is
a major inconvenience, but currently it seems that it's
either this method or sticking with the current Thunderbird
version and Enigmail.
