I saw one detail after I pressed Send. This appears to be a persistent
flaw in my e-mail writing.

I think keys 1, 2 and 3 are all subkeys; NOT your primary. To extend the
primary, don't issue a "key" command before "expire". Only after that
extend the subkeys.



I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
