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.

A tiny lib (Less than 10 methods) to store constants where attackers will have a harder time to find.

This library uses an annotationProcessor to store the constants in a new file (where the constants are encrypted), and via JNI it will later retrieve them decoding them inside the .so file.

This way the attackers cant know the encoding system (because its inside the annotation processor), neither the decoding.

One tool to manage key generation, key storing and encryption on different APIs of Android.

As you may know android provided API to use keystore that is stored in system only from API 18. They introduced AndroidKeyStore provider that is responsible to manage this.

But as always there are underwater stones. Up to API 23 you are only able to create asymmetric keys using AndroidKeyStore provider. Also algorithms that you can use are limited. And what about devices below API 18 ?

This project provides API that wraps default JCA api and AndroidKeyStore API and makes it easy to create, manage and use your keys on any andorid API.
