We should be phasing out all rsa based keys. Please update all keys to use an ed25519 key and remove the old rsa keys. This will include service accounts and user accounts.
User account keys will need documentation so that the end users (many not heavily technical) can update their ssh config to use the new keys.
All service account keys have been updated to ed25519. Need to do the documentation and notification for user keys. We have 27 user accounts still using rsa keys.
going to try and work through the advancement users at the offsite next month. Just need them to generate an updated key and update their ssh config file. Perhaps we can use an unconference section for that.
