Method Details

engineGeneratePublic

protected PublicKey engineGeneratePublic(KeySpec keySpec)
                                  throws InvalidKeySpecException

Specified by:

engineGeneratePublic in class KeyFactorySpi

Throws:

InvalidKeySpecException

engineGeneratePrivate

protected PrivateKey engineGeneratePrivate(KeySpec keySpec)
                                    throws InvalidKeySpecException

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

Specified by:

engineGeneratePrivate in class KeyFactorySpi

Throws:

InvalidKeySpecException

engineGetKeySpec

protected <T extends KeySpec> T engineGetKeySpec(Key key,
 Class<T> keySpec)
                                          throws InvalidKeySpecException

Specified by:

engineGetKeySpec in class KeyFactorySpi

Throws:

InvalidKeySpecException

engineTranslateKey

protected Key engineTranslateKey(Key key)
                          throws 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.

Specified by:

engineTranslateKey in class KeyFactorySpi

Throws:

InvalidKeyException
