final class RSASigningPrivateCrtKey
extends SigningPrivateKey

A SigningPrivateKey that retains the Chinese Remainder Theorem parameters, so it can be converted back to a Java CRT key. By preserving the CRT parameters across a Java to I2P to Java conversion, we speed up signing by about 3.3x, and the parameters are correctly serialized in PEM format when stored to a keystore. The CRT parameters are NOT retained when this object is serialized via getData().
