This provides the optional parameters that can be specified for KeyStore entries that work with Android KeyStore facility. The Android KeyStore facility is accessed through a Java.Security.KeyStore API using the AndroidKeyStore provider. The context passed in may be used to pop up some UI to ask the user to unlock or initialize the Android KeyStore facility.

Any entries placed in the KeyStore may be retrieved later. Note that there is only one logical instance of the KeyStore per application UID so apps using the sharedUid facility will also share a KeyStore.

Keys may be generated using the Java.Security.KeyPairGenerator facility with a Android.Security.KeyPairGeneratorSpec to specify the entry's alias. A self-signed X.509 certificate will be attached to generated entries, but that may be replaced at a later time by a certificate signed by a real Certificate Authority.
