I have a wallet on an offline computer, which has too many backups on connected computers.
I would like to generate a totally new bitcoin address on the offline computer, and use it as a cold storage address. I will then sign an offline transaction from the wallet to that new address and be safe.
How can I create a new Bitcoin private key from the Bitcoin CLI, without using any existing wallet keys / addresses?
I've looked into getnewaddress, but it seems to be getting the keys from the keypool on the existing wallet.
Note - I know I can use bitaddress.org offline, but I would like to use the basic bitcoin-core tools for this one.
