PGP Question
@se7en I believe you have. That's not a fatal problem. But it could be annoying if you generated those keys on hardware devices.
Re: Web-of-Trust, the web-of-trust attests to identities, via the master key. So adding new subkeys doesn't break it.
Re: expiration, you absolutely can just extend the expiration. I've done that with my key repeatedly.
@se7en Ah, I think I see what you mean. Yes, letting those keys expire, as well as extending the expiration, is fine. And as I said, changes to subkeys doesn't affect the WoT.
Sounds like you already know understand this fully, but note that the recipients actually need to get a copy of your updated key for any of this to take effect from their perspective. So in practice, push it to keyservers (which are kinda broken these days...) and/or send a copy directly.
I hope that helps!
