Keychain Plugin for Apache Cordova

created by David Williams (ADI Health) extending work by Shazron Abdullah (Copyright 2012) to include support for Android Keystore (modified by Venelin Venelinov to use AES encryption for Android to store bigger strings than 246 characters). Requires Android API level 18 (4.3) for Keystore support

Apache 2.0 License except for the SFHFKeychainUtils code that is under src/ios/SFHFKeychainUtils

Follows the Cordova Plugin spec, so that it works with Plugman, or you can install it manually below.

Manually importing the plugin is not supported anymore, please use Plugman or the Cordova CLI tool

The "Keychain" object definition is installed globally.

The plugin's JavaScript functions are called after creating the plugin object thus:

    var kc = new Keychain();
    kc.getForKey(win, fail, "some_key", "some_servicename");

iCloud keychain enabled

iCloud keychain synchonizing is enabled, so the keychain will be mirrored across all devices if the user is signed in to iCloud (Settings > iCloud) and has iCloud keychain turned on (Settings > iCloud > Keychain)

Usage

Important:

If you are saving a JSON string value in setForKey, for example after applying JSON.stringify on an object, you must escape the characters in that string, if not you cannot retrieve it using getForKey.

var obj = { foo: 'bar' };
var value = JSON.stringify(obj);
value = value
      .replace(/[\\]/g, '\\\\')
      .replace(/[\"]/g, '\\\"')
      .replace(/[\/]/g, '\\/')
      .replace(/[\b]/g, '\\b')
      .replace(/[\f]/g, '\\f')
      .replace(/[\n]/g, '\\n')
      .replace(/[\r]/g, '\\r')
      .replace(/[\t]/g, '\\t');

See the example folder for example usage.

// Get a reference to the plugin first
// Use optional string parameter 'encryptionRequired' to specify if Android keys should be stored encrypted
// (no affect on iOS)
// Keychain() or Keychain('true') will use encryption to store keys
// Keychain('false') will store unencrypted keys
// If Android screen lock is not configured then an attempt to use Keychain with encrypted keys will fail with error:
// "failed: Android keystore must be in initialized and unlocked state if encryption is required"
var kc = new Keychain();
