You can, since it is flexible in what you can store. If you directly rely
on public key based addressing like with Tor, I2P, CJDNS and more, then the
verification is automatic - the connection will only succeed if the server
has the right private key.

For other systems, you need to create new plugins that do the verification
at some level where the client software can understand the result. Usually
that means you have to proxy most software and often also have the proxy
confirm the certificates in a MITM fashion.
