I have a question regarding how we should store cold keys while creating/managing a stake pool.
The below image is taken from the guide here: https://docs.cardano.org/projects/cardano-node/en/latest/stake-pool-operations/node_keys.html
The guide suggests that we should store the cold keys in a computer that is not connected to the Internet and only upload the kes and vrf keys to the servers that run the nodes.
But when we register a stake pool, we need both “cold.vkey” and “cold.skey”, and this made me very confused. In the end, I had to upload the cold keys to the server and then deleted it after registering the stake pool.
Can anyone suggest what would be the best practises in managing these cold keys?
