Forgive me, but I am fairly inexperienced with PGP. I successfully created a key pair and have been using it for nearly 3 years. But I have run into an issue. I extended the expiration date about a year ago, but now our partner wants us to create a new one with a 2 yr expiration date.
So, I have a couple of questions regarding creating a new key before the current one expires. We send multiple files to a bank many times a day. When I installed PGP, I created the initial key pair, then extended the expiration date. Now, it is set to expire in few weeks, and they do not want me to extend the expiration date any more. I want to keep using the old key while creating a new one for use once the bank gets it loaded. The bank said it could take a few days and we don't want to interrupt our transmissions.
So, is it as simple as just doing a command --gen-key with a different user and passphrase than my initial key pair 2 years ago? Keep in mind, again, I don't want to interfere with our current keys. I would continue to send the bank files with our old key until they get it loaded. Then a couple days before expiring, I would start using the new key.
Then, once the expiration date passes and the bank has loaded our other key, would I do a --remove-key-pair command to remove my initial key pair leaving only our new one?
Thank you in advance.
