Constructor Detail

JCESecretKeyFactory

protected JCESecretKeyFactory(java.lang.String algName)
Method Detail

engineGenerateSecret

protected SecretKey engineGenerateSecret(java.security.spec.KeySpec keySpec)
                                  throws java.security.spec.InvalidKeySpecException
Description copied from class: SecretKeyFactorySpi
Generates a SecretKey object from the provided key specification (key material).
Overrides:
engineGenerateSecret in class SecretKeyFactorySpi
Following copied from class: javax.crypto.SecretKeyFactorySpi
Parameters:
keySpec - the specification (key material) of the secret key
Returns:
the secret key
Throws:
java.security.spec.InvalidKeySpecException - if the given key specification is inappropriate for this secret-key factory to produce a secret key.

engineGetKeySpec

protected java.security.spec.KeySpec engineGetKeySpec(SecretKey key,
                                                      java.lang.Class keySpec)
                                               throws java.security.spec.InvalidKeySpecException
Description copied from class: SecretKeyFactorySpi
Returns a specification (key material) of the given key object in the requested format.
Overrides:
engineGetKeySpec in class SecretKeyFactorySpi
Following copied from class: javax.crypto.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:
java.security.spec.InvalidKeySpecException - if the requested key specification is inappropriate for the given key (e.g., the algorithms associated with key and keySpec do not match, or key references a key on a cryptographic hardware device whereas keySpec is the specification of a software-based key), or the given key cannot be dealt with (e.g., the given key has an algorithm or format not supported by this secret-key factory).

engineTranslateKey

protected SecretKey engineTranslateKey(SecretKey key)
                                throws java.security.InvalidKeyException
Description copied from class: SecretKeyFactorySpi
Translates a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this secret-key factory.
Overrides:
engineTranslateKey in class SecretKeyFactorySpi
Following copied from class: javax.crypto.SecretKeyFactorySpi
Parameters:
key - the key whose provider is unknown or untrusted
Returns:
InvalidKeyException if the given key cannot be processed by this secret-key factory.
