DTLS packet peer.
</brief_description>
<description >
This class represents a DTLS peer connection. It can be used to connect to a DTLS server, and is returned by [method DTLSServer.take_connection].

[b]Warning:[/b] SSL/TLS certificate revocation and certificate pinning are currently not supported. Revoked certificates are accepted as long as they are otherwise valid. If this is a concern, you may want to use automatically managed certificates with a short validity period.

<description >
Connects a [code]peer[/code] beginning the DTLS handshake using the underlying [PacketPeerUDP] which must be connected (see [method PacketPeerUDP.connect_to_host]). If [code]validate_certs[/code] is [code]true[/code], [PacketPeerDTLS] will validate that the certificate presented by the remote peer and match it with the [code]for_hostname[/code] argument. You can specify a custom [X509Certificate] to use for validation via the [code]valid_certificate[/code] argument.
