Handler for servers using a X25519 key exchange to perform authentication via a set of authorized (public) keys of clients.
This follows the method described in X25519AuthenticationHandler
. Once all these checks have succeeded, it will check whether the public key of the client is in the list of authorized keys to login.

Checks whether this handler can be used with the current configuration.
For example when there is no password, the handler cannot be used.
