But the key owner is always online, for in practice,
certs are always used for https.
Arguably we should be using not-necessarily-online certs
to sign email, but the email that arguably needs
signing, for example emails from amazon.com, are never
signed.
The only reason this email is signed is to make a point
about technology, not because the signature serves any
useful purpose.
