Forge

A native implementation of TLS (and various other cryptographic tools) in JavaScript.

Introduction

The Forge software is a fully native implementation of the TLS protocol in JavaScript as well as a set of tools for developing Web Apps that utilize many network resources.

Performance

Forge is fast. Benchmarks against other popular JavaScript cryptography libraries can be found here:

http://cryptojs.altervista.org/test/simulate-threading-speed_test.html

Getting Started

Node.js

If you want to use forge with node.js, it is available through npm:

https://npmjs.org/package/node-forge

Installation:

npm install node-forge

You can then use forge as a regular module:

var forge = require('node-forge');

Requirements

General
- Optional: GNU autotools for the build infrastructure if using Flash.
Building a Browser Bundle:
- nodejs
- npm
Testing
- nodejs
- Optional: Python and OpenSSL development environment to build
- a special SSL module with session cache support for testing with flash.
- http://www.python.org/dev/
- http://www.openssl.org/
- Debian users should install python-dev and libssl-dev.
Optional: Flash
- A pre-built SocketPool.swf is included.
- Adobe Flex 3 SDK to build the Flash socket code.
- http://opensource.adobe.com/wiki/display/flexsdk/

Building a browser bundle

To create a minimized JavaScript bundle, run the following:

npm install
npm run minify

This will create a single minimized file that can be included in the browser:

js/forge.min.js

Include the file via:

<script src="js/forge.min.js"></script>

Note that the minify script depends on the requirejs package, and that the requirejs binary 'r.js' assumes that the name of the node binary is 'node' not 'nodejs', as it is on some systems. You may need to change the hashbang line to use 'nodejs' or run the command manually.

To create a single non-minimized file that can be included in the browser:

npm install
npm run bundle

This will create:

js/forge.bundle.js

Include the file via:

<script src="js/forge.bundle.js"></script>

The above bundles will synchronously create a global 'forge' object.

Keep in mind that these bundles will not include any WebWorker scripts (eg: prime.worker.js) or their dependencies, so these will need to be accessible from the browser if any WebWorkers are used.

Testing with NodeJS & RequireJS

A test server for node.js can be found at ./nodejs. The following are included:

Example of how to use forge within NodeJS in the form of a mocha test.
Example of how to serve forge to the browser using RequireJS.

To run:

cd nodejs
npm install
npm test
npm start

Old build system that includes flash support

To build the whole project, including Flash, run the following:

$ ./build-setup
$ make

This will create the SWF, symlink all the JavaScript files, and build a Python SSL module for testing. To see configure options, run ./configure --help.

Old test system including flash support

A test server is provided which can be run in TLS mode and non-TLS mode. Use the --help option to get help for configuring ports. The server will print out the local URL you can vist to run tests.

Some of the simplier tests should be run with just the non-TLS server::

$ ./tests/server.py

More advanced tests need TLS enabled::

$ ./tests/server.py --tls

Contributing

Any contributions (eg: PRs) that are accepted will be brought under the same license used by the rest of the Forge project. This license allows Forge to be used under the terms of either the BSD License or the GNU General Public License (GPL) Version 2.

See: LICENSE

If a contribution contains 3rd party source code with its own license, it may retain it, so long as that license is compatible with the Forge license.

Documentation

If at any time you wish to disable the use of native code, where available, for particular forge features like its secure random number generator, you may set the disableNativeCode flag on forge to true. It is not recommended that you set this flag as native code is typically more performant and may have stronger security properties. It may be useful to set this flag to test certain features that you plan to run in environments that are different from your testing environment.

To disable native code when including forge in the browser:

forge = {disableNativeCode: true};
// now include forge script file(s)
// Note: with this approach, script files *must*
// be included after initializing the global forge var
 
// alternatively, include script files first and then call
forge = forge({disableNativeCode: true});
 
// Note: forge will be permanently reconfigured now;
// to avoid this but use the same "forge" var name,
// you can wrap your code in a function to shadow the
// global var, eg:
(function(forge) {
  // ...
})(forge({disableNativeCode: true}));

To disable native code when using node.js:

var forge = require('node-forge')({disableNativeCode: true});

Transports

### TLS

});
 
// when encrypted TLS data is received from the client, process it
server.process(encryptedBytesFromClient);

Connect to a TLS server using node's net.Socket:

var socket = new net.Socket();
 
var client = forge.tls.createConnection({
  server: false,
  verify: function(connection, verified, depth, certs) {
    // skip verification for testing
    console.log('[tls] server certificate verified');
    return true;
  },
  connected: function(connection) {
    console.log('[tls] connected');
    // prepare some data to send (note that the string is interpreted as
    // 'binary' encoded, which works for HTTP which only uses ASCII, use
    // forge.util.encodeUtf8(str) otherwise
    client.prepare('GET / HTTP/1.0\r\n\r\n');
  },
  tlsDataReady: function(connection) {
    // encrypted data is ready to be sent to the server
    var data = connection.tlsData.getBytes();
    socket.write(data, 'binary'); // encoding should be 'binary'
  },
  dataReady: function(connection) {
    // clear data from the server is ready
    var data = connection.data.getBytes();
    console.log('[tls] data received from the server: ' + data);
  },
  closed: function() {
    console.log('[tls] disconnected');
  },
  error: function(connection, error) {
    console.log('[tls] error', error);
  }
});
 
socket.on('connect', function() {
  console.log('[socket] connected');
  client.handshake();
});
socket.on('data', function(data) {
  client.process(data.toString('binary')); // encoding should be 'binary'
});
socket.on('end', function() {
  console.log('[socket] disconnected');
});
 
// connect to google.com
socket.connect(443, 'google.com');
 
// or connect to gmail's imap server (but don't send the HTTP header above)
//socket.connect(993, 'imap.gmail.com');

### HTTP

Provides a native JavaScript mini-implementation of an http client that uses pooled sockets.

Examples

// create an HTTP GET request
var request = forge.http.createRequest({method: 'GET', path: url.path});
 
// send the request somewhere
sendSomehow(request.toString());
 
// receive response
var buffer = forge.util.createBuffer();
var response = forge.http.createResponse();
var someAsyncDataHandler = function(bytes) {
  if(!response.bodyReceived) {
    buffer.putBytes(bytes);
    if(!response.headerReceived) {
      if(response.readHeader(buffer)) {
        console.log('HTTP response header: ' + response.toString());
      }
    }
    if(response.headerReceived && !response.bodyReceived) {
      if(response.readBody(buffer)) {
        console.log('HTTP response body: ' + response.body);
      }
    }
  }
};

### SSH

Provides some SSH utility functions.

Examples

// encodes (and optionally encrypts) a private RSA key as a Putty PPK file
forge.ssh.privateKeyToPutty(privateKey, passphrase, comment);
 
// encodes a public RSA key as an OpenSSH file
forge.ssh.publicKeyToOpenSSH(key, comment);
 
// encodes a private RSA key as an OpenSSH file
forge.ssh.privateKeyToOpenSSH(privateKey, passphrase);
 
// gets the SSH public key fingerprint in a byte buffer
forge.ssh.getPublicKeyFingerprint(key);
 
// gets a hex-encoded, colon-delimited SSH public key fingerprint
forge.ssh.getPublicKeyFingerprint(key, {encoding: 'hex', delimiter: ':'});

### XHR

Provides an XmlHttpRequest implementation using forge.http as a backend.

Examples

### Sockets

Provides an interface to create and use raw sockets provided via Flash.

Examples

Ciphers

### CIPHER

Provides a basic API for block encryption and decryption. There is built-in support for the ciphers: AES, 3DES, and DES, and for the modes of operation: ECB, CBC, CFB, OFB, CTR, and GCM.

These algorithms are currently supported:

AES-CBC
AES-CFB
AES-OFB
AES-CTR
AES-GCM
3DES-ECB
3DES-CBC
DES-ECB
DES-CBC

When using an AES algorithm, the key size will determine whether AES-128, AES-192, or AES-256 is used (all are supported). When a DES algorithm is used, the key size will determine whether 3DES or regular DES is used. Use a 3DES algorithm to enforce Triple-DES.

Examples

// generate a random key and IV
// Note: a key size of 16 bytes will use AES-128, 24 => AES-192, 32 => AES-256
var key = forge.random.getBytesSync(16);
var iv = forge.random.getBytesSync(16);
 
/* alternatively, generate a password-based 16-byte key
var salt = forge.random.getBytesSync(128);
var key = forge.pkcs5.pbkdf2('password', salt, numIterations, 16);
*/
 
// encrypt some bytes using CBC mode
// (other modes include: CFB, OFB, CTR, and GCM)
var cipher = forge.cipher.createCipher('AES-CBC', key);
cipher.start({iv: iv});
cipher.update(forge.util.createBuffer(someBytes));
cipher.finish();
var encrypted = cipher.output;
// outputs encrypted hex
console.log(encrypted.toHex());
 
// decrypt some bytes using CBC mode
// (other modes include: CFB, OFB, CTR, and GCM)
var decipher = forge.cipher.createDecipher('AES-CBC', key);
decipher.start({iv: iv});
decipher.update(encrypted);
decipher.finish();
// outputs decrypted hex
console.log(decipher.output.toHex());
 
// encrypt some bytes using GCM mode
var cipher = forge.cipher.createCipher('AES-GCM', key);
cipher.start({
  iv: iv, // should be a 12-byte binary-encoded string or byte buffer
  additionalData: 'binary-encoded string', // optional
  tagLength: 128 // optional, defaults to 128 bits
});
cipher.update(forge.util.createBuffer(someBytes));
cipher.finish();
var encrypted = cipher.output;
var tag = cipher.mode.tag;
// outputs encrypted hex
console.log(encrypted.toHex());
// outputs authentication tag
console.log(tag.toHex());
 
// decrypt some bytes using GCM mode
var decipher = forge.cipher.createDecipher('AES-GCM', key);
decipher.start({
  iv: iv,
  additionalData: 'binary-encoded string', // optional
  tagLength: 128, // optional, defaults to 128 bits
  tag: tag // authentication tag from encryption
});
decipher.update(encrypted);
var pass = decipher.finish();
// pass is false if there was a failure (eg: authentication tag didn't match)
if(pass) {
  // outputs decrypted hex
  console.log(decipher.output.toHex());
}

Using forge in node.js to match openssl's "enc" command line tool (Note: OpenSSL "enc" uses a non-standard file format with a custom key derivation function and a fixed iteration count of 1, which some consider less secure than alternatives such as OpenPGP/GnuPG):

var forge = require('node-forge');
var fs = require('fs');
 
// openssl enc -des3 -in input.txt -out input.enc
function encrypt(password) {
  var input = fs.readFileSync('input.txt', {encoding: 'binary'});
 
  // 3DES key and IV sizes
  var keySize = 24;
  var ivSize = 8;
 
  // get derived bytes
  // Notes:
  // 1. If using an alternative hash (eg: "-md sha1") pass
  //   "forge.md.sha1.create()" as the final parameter.
  // 2. If using "-nosalt", set salt to null.
  var salt = forge.random.getBytesSync(8);
  // var md = forge.md.sha1.create(); // "-md sha1"
  var derivedBytes = forge.pbe.opensslDeriveBytes(
    password, salt, keySize + ivSize/*, md*/);
  var buffer = forge.util.createBuffer(derivedBytes);
  var key = buffer.getBytes(keySize);
  var iv = buffer.getBytes(ivSize);
 
  var cipher = forge.cipher.createCipher('3DES-CBC', key);
  cipher.start({iv: iv});
  cipher.update(forge.util.createBuffer(input, 'binary'));
  cipher.finish();
 
  var output = forge.util.createBuffer();
 
  // if using a salt, prepend this to the output:
  if(salt !== null) {
    output.putBytes('Salted__'); // (add to match openssl tool output)
    output.putBytes(salt);
  }
  output.putBuffer(cipher.output);
 
  fs.writeFileSync('input.enc', output.getBytes(), {encoding: 'binary'});
}
 
// openssl enc -d -des3 -in input.enc -out input.dec.txt
function decrypt(password) {
  var input = fs.readFileSync('input.enc', {encoding: 'binary'});
 
  // parse salt from input
  input = forge.util.createBuffer(input, 'binary');
  // skip "Salted__" (if known to be present)
  input.getBytes('Salted__'.length);
  // read 8-byte salt
  var salt = input.getBytes(8);
 
  // Note: if using "-nosalt", skip above parsing and use
  // var salt = null;
 
  // 3DES key and IV sizes
  var keySize = 24;
  var ivSize = 8;
 
  var derivedBytes = forge.pbe.opensslDeriveBytes(
    password, salt, keySize + ivSize);
  var buffer = forge.util.createBuffer(derivedBytes);
  var key = buffer.getBytes(keySize);
  var iv = buffer.getBytes(ivSize);
 
  var decipher = forge.cipher.createDecipher('3DES-CBC', key);
  decipher.start({iv: iv});
  decipher.update(input);
  var result = decipher.finish(); // check 'result' for true/false
 
  fs.writeFileSync(
    'input.dec.txt', decipher.output.getBytes(), {encoding: 'binary'});
}

Utilities

### Prime

Provides an API for generating large, random, probable primes.

Examples

// generate a random prime on the main JS thread
var bits = 1024;
forge.prime.generateProbablePrime(bits, function(err, num) {
  console.log('random prime', num.toString(16));
});
 
// generate a random prime using Web Workers (if available, otherwise
// falls back to the main thread)
var bits = 1024;
var options = {
  algorithm: {
    name: 'PRIMEINC',
    workers: -1 // auto-optimize # of workers
  }
};
forge.prime.generateProbablePrime(bits, options, function(err, num) {
  console.log('random prime', num.toString(16));
});

### PRNG

Provides a Fortuna-based cryptographically-secure pseudo-random number generator, to be used with a cryptographic function backend, e.g. AES. An implementation using AES as a backend is provided. An API for collecting entropy is given, though if window.crypto.getRandomValues is available, it will be used automatically.

Examples

// get some random bytes synchronously
var bytes = forge.random.getBytesSync(32);
console.log(forge.util.bytesToHex(bytes));
 
// get some random bytes asynchronously
forge.random.getBytes(32, function(err, bytes) {
  console.log(forge.util.bytesToHex(bytes));
});
 
// collect some entropy if you'd like
forge.random.collect(someRandomBytes);
jQuery().mousemove(function(e) {
  forge.random.collectInt(e.clientX, 16);
  forge.random.collectInt(e.clientY, 16);
});
 
// specify a seed file for use with the synchronous API if you'd like
forge.random.seedFileSync = function(needed) {
  // get 'needed' number of random bytes from somewhere
  return fetchedRandomBytes;
};
 
// specify a seed file for use with the asynchronous API if you'd like
forge.random.seedFile = function(needed, callback) {
  // get the 'needed' number of random bytes from somewhere
  callback(null, fetchedRandomBytes);
});
 
// register the main thread to send entropy or a Web Worker to receive
// entropy on demand from the main thread
forge.random.registerWorker(self);
 
// generate a new instance of a PRNG with no collected entropy
var myPrng = forge.random.createInstance();

### Tasks

Provides queuing and synchronizing tasks in a web application.

Examples

### Utilities

Provides utility functions, including byte buffer support, base64, bytes to/from hex, zlib inflate/deflate, etc.

Examples

// encode/decode base64
var encoded = forge.util.encode64(str);
var str = forge.util.decode64(encoded);
 
// encode/decode UTF-8
var encoded = forge.util.encodeUtf8(str);
var str = forge.util.decodeUtf8(encoded);
 
// bytes to/from hex
var bytes = forge.util.hexToBytes(hex);
var hex = forge.util.bytesToHex(bytes);
 
// create an empty byte buffer
var buffer = forge.util.createBuffer();
// create a byte buffer from raw binary bytes
var buffer = forge.util.createBuffer(input, 'raw');
// create a byte buffer from utf8 bytes
var buffer = forge.util.createBuffer(input, 'utf8');
 
// get the length of the buffer in bytes
buffer.length();
// put bytes into the buffer
buffer.putBytes(bytes);
// put a 32-bit integer into the buffer
buffer.putInt32(10);
// buffer to hex
buffer.toHex();
// get a copy of the bytes in the buffer
bytes.bytes(/* count */);
// empty this buffer and get its contents
bytes.getBytes(/* count */);
 
// convert a forge buffer into a node.js Buffer
// make sure you specify the encoding as 'binary'
var forgeBuffer = forge.util.createBuffer();
var nodeBuffer = new Buffer(forgeBuffer.getBytes(), 'binary');
 
// convert a node.js Buffer into a forge buffer
// make sure you specify the encoding as 'binary'
var nodeBuffer = new Buffer();
var forgeBuffer = forge.util.createBuffer(nodeBuffer.toString('binary'));
 
// parse a URL
var parsed = forge.util.parseUrl('http://example.com/foo?bar=baz');
// parsed.scheme, parsed.host, parsed.port, parsed.path, parsed.fullHost

### Logging

Provides logging to a javascript console using various categories and levels of verbosity.

Examples

### Debugging

Provides storage of debugging information normally inaccessible in closures for viewing/investigation.

Examples

### Flash Socket Policy Module

Provides an Apache module "mod_fsp" that can serve up a Flash Socket Policy. See mod_fsp/README for more details. This module makes it easy to modify an Apache server to allow cross domain requests to be made to it.
