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.
