Usage in Deno
import * as mod from "node:tls";
The node:tls
module provides an implementation of the Transport Layer Security
(TLS) and Secure Socket Layer (SSL) protocols that is built on top of OpenSSL.
The module can be accessed using:
const tls = require('node:tls');
Verifies the certificate cert
is issued to hostname
.
The callback
function, if specified, will be added as a listener for the 'secureConnect'
event.
createServer sets the default value of the honorCipherOrder
option
to true
, other APIs that create secure contexts leave it unset.
Creates a new Server. The secureConnectionListener
, if provided, is
automatically set as a listener for the 'secureConnection'
event.
Returns an array with the names of the supported TLS ciphers. The names are
lower-case for historical reasons, but must be uppercased to be used in
the ciphers
option of createSecureContext.
Creates a new secure pair object with two streams, one of which reads and writes the encrypted data and the other of which reads and writes the cleartext data. Generally, the encrypted stream is piped to/from an incoming encrypted data stream and the cleartext one is used as a replacement for the initial encrypted stream.
The default value of the ciphers option of tls.createSecureContext(). It can be assigned any of the supported OpenSSL ciphers. Defaults to the content of crypto.constants.defaultCoreCipherList, unless changed using CLI options using --tls-default-ciphers.
The default curve name to use for ECDH key agreement in a tls server. The default value is 'auto'. See tls.createSecureContext() for further information.
The default value of the maxVersion option of tls.createSecureContext(). It can be assigned any of the supported TLS protocol versions, 'TLSv1.3', 'TLSv1.2', 'TLSv1.1', or 'TLSv1'. Default: 'TLSv1.3', unless changed using CLI options. Using --tls-max-v1.2 sets the default to 'TLSv1.2'. Using --tls-max-v1.3 sets the default to 'TLSv1.3'. If multiple of the options are provided, the highest maximum is used.
The default value of the minVersion option of tls.createSecureContext(). It can be assigned any of the supported TLS protocol versions, 'TLSv1.3', 'TLSv1.2', 'TLSv1.1', or 'TLSv1'. Default: 'TLSv1.2', unless changed using CLI options. Using --tls-min-v1.0 sets the default to 'TLSv1'. Using --tls-min-v1.1 sets the default to 'TLSv1.1'. Using --tls-min-v1.3 sets the default to 'TLSv1.3'. If multiple of the options are provided, the lowest minimum is used.
An immutable array of strings representing the root certificates (in PEM format) used for verifying peer certificates. This is the default value of the ca option to tls.createSecureContext().
