Method Detail

engineGenerateSecret

protected SecretKey engineGenerateSecret(java.security.spec.KeySpec spec)
                                  throws java.security.spec.InvalidKeySpecException

Description copied from class: SecretKeyFactorySpi

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

Specified by:

engineGenerateSecret in class SecretKeyFactorySpi

Parameters:

spec - 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 clazz)
                                               throws java.security.spec.InvalidKeySpecException

Description copied from class: SecretKeyFactorySpi

Returns a specification (key material) of the given key object in the requested format.

Specified by:

engineGetKeySpec in class SecretKeyFactorySpi

Parameters:

key - the key

clazz - 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)

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.

Specified by:

engineTranslateKey in class 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.
