`keyserv` is a little utility I wrote to dispense *age* keys to clients.
It uses SSH certificates for authentication. If the client presents an
SSH certificate signed by a trusted key, the server will return all the
keys the principal(s) listed in the certificate are allowed to use. The
response is encrypted with the public key from the certificate, so the
client must have access to the corresponding private key in order to
read the response.
I am currently using this server to provide keys for the new
configuration policy. The keys herein are used to encrypt NUT monitor
passwords.
