Throws:

java.security.spec.InvalidKeySpecException

engineGeneratePrivate

                                                  throws java.security.spec.InvalidKeySpecException

We don't support RSAPrivateKeySpec because it doesn't have enough information. You need to provide an RSAPrivateCrtKeySpec.

engineTranslateKey

protected java.security.Key engineTranslateKey(java.security.Key key)
                                        throws java.security.InvalidKeyException

Translates key by calling getEncoded() to get its encoded form, then importing the key from its encoding. Two formats are supported: "X.509", which is decoded with an X509EncodedKeySpec; and "PKCS#8", which is decoded with a PKCS8EncodedKeySpec.

This method is not well standardized: the documentation is very vague about how the key is supposed to be translated. It is better to move keys around by wrapping and unwrapping them; or by manually translating to a KeySpec, then manually translating back to a Key.
