I have chosen RSA as a “known good” algorithm for the primary key
because if I chose a different curve or algorithm for elliptic key once
I have the required knowledge to make an informed decision it will be
more convenient to change only a subkey than to generate a new primary
key. For example, I can keep the signatures (certifications) that I
accumulate during that time on my key, supposing I have the opportunity
to go to a signing party.
Also, using a subkey for signing still has a size advantage. If you
have, say, 5 keys signed by my ECC subkey. there will be less size
Anyway, my question still stands: How can I enable the certificate
capability on a subkey with GPG?
