ssl-config

SSL Config

A node.js implementation of the recommended cipher suites and TLS/SSL versions from Mozilla's Server Side TLS project.

Note this package only sets cipher suites and TLS/SSL versions, other parts of the recommendations are implemented elsewhere, eg, for Express servers HSTS we recommend using Helmet.

Usage

Just use either 'modern', 'intermediate' or 'old'.

modern

Firefox 27, Chrome 22, IE 11, Opera 14, Safari 7, Android 4.4, Java 8 and newer.

intermediate

Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7 and newer.

old

Windows XP IE6, Java 6 and newer. You really shouldn't use this setting, it is implemented for completeness.

Eg:

var sslConfig = require('ssl-config')('high');

Then run https.createServer per node.js TLS and io.js TLS docs.

https.createServer({
	key: privateKey,
	cert: certificate,
	ca: certificateAuthority,
	ciphers: sslConfig.ciphers,
	secureOptions: sslConfig.secureOptions
});

Or for express.js

var server = https.createServer({
	key: privateKey,
	cert: certificate,
	ca: certificateAuthority,
	ciphers: sslConfig.ciphers,
	secureOptions: sslConfig.secureOptions
}, app);
