Creating the perfect GPG keypair - Alex Cabal

To save this post, select a stash from drop-down menu or type in a new one:

There’s a lot of information online on how to create a new GPG keypair. Unfortunately a lot of it is old advice and recommends settings that today might be unsafe.

There also isn’t too much information on how to protect your keypair if you use a laptop that might get lost or stolen.

Protecting your keypair on a laptop is tricky. On one hand, you need your private key with you to decrypt or sign messages.

On the other hand, if your laptop is stolen then you risk losing your entire online identity, perhaps going back years, because the thief would have access to your private key and could then impersonate you.

You’d think that today, where laptops and world travel are commonplace, there’d be a little more information on how to secure a private key you have to travel with. But I could only find one resource: the Debian Wiki entry on subkeys. Fortunately it turns out this wiki page has exactly the solution we need.

I'm weary of the word "perfect".
