I have generated 2 key pairs in another app without passwords, and while I am able to import them into gpg using --batch
after they are imported I would like to set a password on them, or create revocation keys for both of the key pairs
but unfortunately, gpg-agent? asks for passwords for both private keys, even if there was no password assigned, and fails on empty strings
Please advise: how can I set passwords on these existing keys, or generate revocation keys for them?
