Secured-Preference-Store
A SharedPreferences wrapper for Android that encrypts the content with 256 bit AES encryption. The Encryption key is securely stored in device's KeyStore. You can also use the EncryptionManager class to encrypt & decrypt data out of the box.
##Setup ###Maven
<dependency>
<groupId>online.devliving</groupId>
<artifactId>securedpreferencestore</artifactId>
<version>0.2.3</version>
<type>pom</type>
</dependency>
###Gradle
compile 'online.devliving:securedpreferencestore:0.2.3'
##Usage
You can use the secured preference store just like the way you use the default SharedPrefences
SecuredPreferenceStore prefStore = SecuredPreferenceStore.getSharedInstance(getApplicationContext());
String textShort = prefStore.getString(TEXT_1, null);
String textLong = prefStore.getString(TEXT_2, null);
int numberInt = prefStore.getInt(NUMBER_1, 0);
prefStore.edit().putString(TEXT_1, text1.length() > 0 ? text1.getText().toString() : null).apply();
prefStore.edit().putString(TEXT_2, text2.length() > 0 ? text2.getText().toString() : null).apply();
prefStore.edit().putInt(NUMBER_1, number1.length() > 0 ? Integer.parseInt(number1.getText().toString().trim()) : 0).commit();You can use the EncryptionManager to encrypt/decrypt data on your own:
EncryptionManager encryptionManager = new EncryptionManager(getApplicationContext(), getSharedPreferences("my_pref", MODE_PRIVATE));
EncryptionManager.EncryptedData encryptedData = encryptionManager.encrypt(bytesToEncrypt);
byte[] decryptedData = encryptionManager.decrypt(encryptedData);##Sample file content A sample secured preference file will look like:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
