This provider was separated out of {@link AndroidKeyStoreProvider} to work around the issue * that Bouncy Castle provider incorrectly declares that it accepts arbitrary keys (incl.

This causes JCA to select the Bouncy Castle's implementation of JCA crypto * operations for Android KeyStore keys unless Android KeyStore's own implementations are installed * as higher-priority than Bouncy Castle ones. The purpose of this provider is to do just that: to * offer crypto operations operating on Android KeyStore keys and to be installed at higher priority * than the Bouncy Castle provider. * *

Once Bouncy Castle provider is fixed, this provider can be merged into the * {@code AndroidKeyStoreProvider}. * * @hide */ class AndroidKeyStoreBCWorkaroundProvider extends Provider { // IMPLEMENTATION NOTE: Class names are hard-coded in this provider to avoid loading these // classes when this provider is instantiated and installed early on during each app's // initialization process. private static final String PACKAGE_NAME = "android.security.keystore";
