realm-encryption-helper

This is a lightweight library to generate a 64-bit random key and using AES Algorithm to encrypt/decrypt that random number to get a Secret Key and save it to Key Store.

This library especially supports for Realm Encryption. That means when using you don't have to care about how to get a random key, where to save that key for safe,... this library will take it.

Support all android version

Setup and using

1. Add library to your build.gradle in app level

implementation 'com.github.tntkhang:realm-encryption-helper:1.0.2'

2.In your CustomeApplication where you init your Realm

// Config RealmEncryptionHelper
RealmEncryptionHelper realmEncryptionHelper = RealmEncryptionHelper.initHelper(this, getString(R.string.app_name));

// Config Realm
Realm.init(this);
RealmConfiguration config = new RealmConfiguration.Builder()
         .name("realm_encrypt.realm")
         .encryptionKey(realmEncryptionHelper.getEncryptKey()) // Call realmEncryptionHelper to get encrypt key
         .build();
 Realm.setDefaultConfiguration(config);

with this code

realmEncryptionHelper.getEncryptKey()

The library will check and generate a new key if your app doesn't contain the key in Key Store before and then save it to Key Store, otherwise, it will be got from Key Store.
