Java 1.2

serializable

This interface extends RSAPrivateKey and provides a decomposition (based on the Chinese remainder theorem) of the private-key value into the various pieces that comprise it. This interface is useful only if you plan to implement your own cryptographic algorithms. To use this interface, you must have a detailed understanding of the mathematics underlying RSA public-key cryptography. Given a java.security.PrivateKey object, you can use the instanceof operator to determine whether you can safely cast it to an RSAPrivateCrtKey .
