public class KeyFactorySpi1_2 extends KeyFactorySpi

Method Summary
protected PrivateKey	engineGeneratePrivate(KeySpec keySpec) We don't support RSAPrivateKeySpec because it doesn't have enough information.
protected PublicKey	engineGeneratePublic(KeySpec keySpec)
protected KeySpec	engineGetKeySpec(Key key, Class keySpec)
protected Key	engineTranslateKey(Key key) Translates key by calling getEncoded() to get its encoded form, then importing the key from its encoding.

Method Summary

protected PrivateKey

engineGeneratePrivate(KeySpec keySpec)

We don't support RSAPrivateKeySpec because it doesn't have enough information.

protected Key

engineTranslateKey(Key key)

Translates key by calling getEncoded() to get its encoded form, then importing the key from its encoding.

Method Detail

protected PrivateKey engineGeneratePrivate(KeySpec keySpec)

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

protected PublicKey engineGeneratePublic(KeySpec keySpec)

protected KeySpec engineGetKeySpec(Key key, Class keySpec)

protected Key engineTranslateKey(Key key)

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.
