Class EngineFactory<T_WRAPPER extends EngineWrapper<JcePrimitiveT>,JcePrimitiveT>

java.lang.Object

com.google.crypto.tink.subtle.EngineFactory<T_WRAPPER,JcePrimitiveT>

public final class EngineFactory<T_WRAPPER extends EngineWrapper<JcePrimitiveT>,JcePrimitiveT>
extends Object

A factory that returns JCE engines, using pre-specified j.security.Providers.

This class contains a lot of static factories and static functions returning factories: these allow customization and hide the typing complexity in this class. To use this class, import it, and replace your Cipher.getInstance(...) with EngineFactory.CIPHER.getInstance(...).

Since:

1.0.0
