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
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
Keys may be generated using the
KeyPairGenerator facility with a
KeyPairGeneratorSpec to specify the entry's

boolean isEncryptionRequired ()
true if the
KeyStore entry must be encrypted at rest. This will protect the entry with the secure lock screen credential (e.g., password, PIN, or pattern).
Note that encrypting the key at rest requires that the secure lock screen (e.g., password, PIN, pattern) is set up, otherwise key generation will fail. Moreover, this key will be deleted when the secure lock screen is disabled or reset (e.g., by the user or a Device Administrator). Finally, this key cannot be used until the user unlocks the secure lock screen after boot.
