A password manager for your keys; a key manager for your soul.
Private ssh-keys are kinda broken. Because of this, poke attempts to circument the problems by storing keys in a different format, encrypted in a lockchain keystore. You can create new keys and store them directly in this store with the poke cli.
poked is an ssh-agent daemon which serves unencrypted keys from the keystore. Each key is never held in memory for longer than the operation it is required for.
After unlocking poked, use a yubikey to re-encrypt the primary key for re-use
