PrefSecure

Android Library for saving any Sensitive Data (e.g user credentials, access token, credit cards ,... etc) in cryptographic format

It is useful espically in case of rooted device, as the hacker can access your SharedPreferences and reach sensitive data easily. So this is a solution to keep your Data Safe.

Usage

1. Init the Singleton in your Application Class by adding this line to the onCreate() Method in order to provide the Application Context in which this Singleton will operate.

@Override
public void onCreate() {
    super.onCreate();

    // Initialize the SecurePref Singleton..
    SecurePref.init(this);
}
  

2. Now you can use SecurePref Singleton all over the app by just Calling SecurePref.getInstance()
3. The APIs of SecurePref is the same as the SharedPreference apis. If you want for example set accountNumber as a secure data you can do this:

SecurePref.getInstance().edit()
          .putLong("accountNumber", 123254589921L)
          .commit();

and you can retreive the accountNumber later using this line:

SecurePref.getInstance().getLong("accountNumber", 0L);

Gradle Dependency

1. Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:

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

2. Add the dependency

dependencies {
	compile 'com.github.Mohamed-Fadel:PrefSecure:0.1.1'
}

Warning

• Supports +14 APIs but only encrypt the data for +18 APIs while save it as a plainText not encrypted for APIs < 18
• Encrypt only the values not the keys.
