		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.

		<method name="disconnect_from_peer">
			<return type="void" />
			<description>
				Disconnects this peer, terminating the DTLS session.
			</description>
		</method>
		<method name="get_status" qualifiers="const">
			<return type="int" enum="PacketPeerDTLS.Status" />
			<description>
				Returns the status of the connection. See [enum Status] for values.
			</description>
		</method>
		<method name="poll">
			<return type="void" />
			<description>
				Poll the connection to check for incoming packets. Call this frequently to update the status and keep the connection working.
