PacketPeerDTLS

Inherits: PacketPeer < RefCounted < Object

DTLS packet peer.

Description

This class represents a DTLS peer connection. It can be used to connect to a DTLS server, and is returned by DTLSServer.take_connection.

Note: When exporting to Android, make sure to enable the INTERNET permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.

Warning: 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.

Enumerations

enum Status:

Status STATUS_DISCONNECTED = 0

A status representing a PacketPeerDTLS that is disconnected.

Status STATUS_HANDSHAKING = 1

A status representing a PacketPeerDTLS that is currently performing the handshake with a remote peer.

Status STATUS_CONNECTED = 2

A status representing a PacketPeerDTLS that is connected to a remote peer.

Status STATUS_ERROR = 3

A status representing a PacketPeerDTLS in a generic error state.

Status STATUS_ERROR_HOSTNAME_MISMATCH = 4

An error status that shows a mismatch in the DTLS certificate domain presented by the host and the domain requested for validation.


Method Descriptions

Error connect_to_peer ( PacketPeerUDP packet_peer, bool validate_certs=true, String for_hostname="", X509Certificate valid_certificate=null )

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


void disconnect_from_peer ( )

Disconnects this peer, terminating the DTLS session.


Status get_status ( ) const

Returns the status of the connection. See Status for values.


void poll ( )

Poll the connection to check for incoming packets. Call this frequently to update the status and keep the connection working.
