Android BasicAndroidKeyStore Sample =================================== An advanced sample displaying the creation and usage of data integrity mechanisms Introduction ------------ This sample demonstrates how to use the Android [KeyStore][1] to safely create and store encryption keys that only your application can access. A [KeyPair][2] consisting of a [PrivateKey][3] and a [PublicKey][4] is being generated. The private key then is being used to sign and verify a String. Below Android M, this sample uses a [KeyPairGeneratorSpec][5] to generate a key pair. On newer versions of Android, a [KeyGenParameterSpec][6] generates a key pair with additional restrictions and properties. Next to that appropriate exception handling for potential errors is being displayed.
