Use a TLSOptions configuration object which is created via static functions. - "TLSOptions.client": uses the standard CA and common name verification. - "TLSOptions.client_unsafe": uses optional CA verification (i.e. if specified) - "TLSOptions.server": is the standard server configuration (chain + key) This will allow us to expand the TLS configuration options to include e.g. mutual authentication without bloating the classes that uses StreamPeerTLS and PacketPeerDTLS as underlying peers.
