Android secure shared preferences using Conceal (Facebook)

• Conceal -> https://github.com/facebook/conceal

Why use ?

• Most of security for data ( as user token, some api key ...)
• Less SharedPreferences file size
• Base on SharedPreferences default, to easy use
• Faster encrypt with the Conceal
• 256-bit encryption

We're supported Conceal 2.x (faster than old version)

Download

#####Gradle:

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url "https://jitpack.io" }
	}
}

Step 2. Add the dependency

        compile 'com.github.KaKaVip:secure-preferences:1.1.0'
        compile 'com.facebook.conceal:conceal:2.0.1@aa'
}

How to use

In Application: Data return empty if you don't setting this

Since v2.0.+ (2017-06-27) you will need to initialize the native library loader. This step is needed because the library loader uses the context. The highly suggested way to do it is in the application class onCreate method like this:

    @Override
    public void onCreate() {
        super.onCreate();
        SecurePreferences.init(this); 
    }

When used:

SharedPreferences prefs = new SecurePreferences.Builder(MainActivity.this)
                .password("password")
                .filename("settings")
                .build();
// Save token
prefs.edit().putString("token","f93ce38ab841fad01bc5e571ea861e9e").apply();

// Get Token
String token = prefs.getString("token","if_not_found");

See settings.xml file:

// SharedPreferences default
<string name="token">f93ce38ab841fad01bc5e571ea861e9e</string>

// Via SecurePreferences
<string name="94a08da1fecbb6e8b46990538c7b50b2">AQI80a7LVHPIW8l00ecIag95oKcaje6U2fgREyvUPTnn3OCBK5rq/xACPjI9</string>
