Method Detail

engineGenerateSecret

protected SecretKey engineGenerateSecret(KeySpec keySpec)
                                  throws InvalidKeySpecException

Generates a SecretKey object from the provided key specification (key material).

Specified by:

engineGenerateSecret in class SecretKeyFactorySpi

Parameters:

keySpec - the specification (key material) of the secret key

Returns:

the secret key

Throws:

InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a public key.

engineGetKeySpec

protected KeySpec engineGetKeySpec(SecretKey key,
                                   Class<?> keySpec)
                            throws InvalidKeySpecException

Specified by:

engineGetKeySpec in class SecretKeyFactorySpi

Parameters:

key - the key

keySpec - 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 SecretKey engineTranslateKey(SecretKey key)
                                throws InvalidKeyException

Translates a SecretKey object, whose provider may be unknown or potentially untrusted, into a corresponding SecretKey object of this key factory.

Specified by:

engineTranslateKey in class SecretKeyFactorySpi

Parameters:

key - the key whose provider is unknown or untrusted

Returns:
