On Android M or newer 5the keys are further encrypted with a master key stored in Android 6Keystore. 7 8It demonstrates the basic steps of using Tink, namely generating or 9loading key material, obtaining a primitive, and using the primitive 10to do crypto. It also shows how one can add a dependency on Tink 11using Gradle. 12 13You can download tink-java source with: 14 15```shell 16git clone https://github.com/tink-crypto/tink-java 17``` 18 19The easiest way to build this app is to import it to [Android Studio](https://developer.android.com/studio/).
