  • Method Details

    • engineGeneratePrivate

      protected PrivateKey engineGeneratePrivate(KeySpec keySpec) throws InvalidKeySpecException
      Generates a private key object from the provided key specification (key material).
      Specified by:
      engineGeneratePrivate in class KeyFactorySpi
      Parameters:
      keySpec - the specification (key material) of the private key (DSAPrivateHWKeySpec is the only accepatble keySpec).
      Returns:
      the newly created DSA private key.
      Throws:
      InvalidKeySpecException - if the provided key specification is not appropriate for this key factory to produce a private key.

    • engineGeneratePublic

      protected PublicKey engineGeneratePublic(KeySpec keySpec) throws InvalidKeySpecException
      Generates a public key object from the provided key specification (key material).
      Specified by:
      engineGeneratePublic in class KeyFactorySpi
      Parameters:
      keySpec - the specification (key material) of the public key.
      Returns:
      the newly created public key.
      Throws:
      InvalidKeySpecException - if the provided key specification is not appropriate for this key factory to produce a public key.

    • engineGetKeySpec

      protected <T extends KeySpec> T engineGetKeySpec(Key key, Class<T> keySpecClass) throws InvalidKeySpecException
      Returns a specification (key material) of the given key in the requested format.
      Specified by:
      engineGetKeySpec in class KeyFactorySpi
      Parameters:
      key - the key
      keySpecClass - the requested format in which the key material shall be returned
      Returns:
      the underlying key specification (key material) in the requested format
      Throws:
      InvalidKeySpecException - if the requested key specification is inappropriate for the given key, or the given key cannot be processed (e.g., the given key has an unrecognized algorithm or format).

    • engineTranslateKey

      protected Key engineTranslateKey(Key key) throws InvalidKeyException
      Translates a Key object, whose provider may be unknown or potentially untrusted, into a corresponding Key object of this key factory.
      Specified by:
      engineTranslateKey in class KeyFactorySpi
      Parameters:
      key - the key whose provider is unknown or untrusted
      Returns:
      the translated key
      Throws:
      InvalidKeyException - if the given key cannot be processed by this key factory.
