TLSOptions

Inherits: RefCounted < Object

TLS configuration for clients and servers.

Description

TLSOptions abstracts the configuration options for the StreamPeerTLS and PacketPeerDTLS classes.

Objects of this class cannot be instantiated directly, and one of the static methods client, client_unsafe, or server should be used instead.

GDScript

# Create a TLS client configuration which uses our custom trusted CA chain.
var client_trusted_cas = load("res://my_trusted_cas.crt")
var client_tls_options = TLSOptions.client(client_trusted_cas)
# Create a TLS server configuration.
var server_certs = load("res://my_server_cas.crt")
var server_key = load("res://my_server_key.key")
var server_tls_options = TLSOptions.server(server_key, server_certs)

Methods

Method Descriptions

TLSOptions client(trusted_chain: X509Certificate = null, common_name_override: String = “”) static 🔗

Creates a TLS client configuration which validates certificates and their common names (fully qualified domain names).

You can specify a custom trusted_chain of certification authorities (the default CA list will be used if null), and optionally provide a common_name_override if you expect the certificate to have a common name other than the server FQDN.

Note: On the Web platform, TLS verification is always enforced against the CA list of the web browser. This is considered a security feature.

TLSOptions client_unsafe(trusted_chain: X509Certificate = null) static 🔗

Creates an unsafe TLS client configuration where certificate validation is optional. You can optionally provide a valid trusted_chain, but the common name of the certificates will never be checked. Using this configuration for purposes other than testing is not recommended.

Note: On the Web platform, TLS verification is always enforced against the CA list of the web browser. This is considered a security feature.

String get_common_name_override() const 🔗

Returns the common name (domain name) override specified when creating with client.

X509Certificate get_own_certificate() const 🔗

Returns the X509Certificate specified when creating with server.

CryptoKey get_private_key() const 🔗

Returns the CryptoKey specified when creating with server.

X509Certificate get_trusted_ca_chain() const 🔗

Returns the CA X509Certificate chain specified when creating with client or client_unsafe.

bool is_server() const 🔗

Returns true if created with server, false otherwise.

bool is_unsafe_client() const 🔗

Returns true if created with client_unsafe, false otherwise.

TLSOptions server(key: CryptoKey, certificate: X509Certificate) static 🔗

Creates a TLS server configuration using the provided key and certificate.

Note: The certificate should include the full certificate chain up to the signing CA (certificates file can be concatenated using a general purpose text editor).
