DESKeyFactory
()
Verify the SunJCE provider in the constructor.
Protected Methods
protected
SecretKey
engineGenerateSecret
(KeySpec keySpec)
Generates a SecretKey object from the provided key
specification (key material).
Parameters
| keySpec
| the specification (key material) of the secret key |
Throws
| InvalidKeySpecException
| if the given key specification
is inappropriate for this key factory to produce a public key.
|
protected
KeySpec
engineGetKeySpec
(SecretKey key, Class keySpec)
Returns a specification (key material) of the given key
in the requested format.
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).
|
Translates a SecretKey object, whose provider may be
unknown or potentially untrusted, into a corresponding
SecretKey object of this key factory.
Parameters
| key
| the key whose provider is unknown or untrusted |
