- public class BlowfishKeyFactory
- extends SecretKeyFactorySpi
This class is used to convert Blowfish keys into a format usable by the
usable by the ABA provider. The supported KeySpec classes are
BlowfishKeySpec and SecretKeySpec. In the case of the SecretKeySpec
the key data must not be encoded. The supported Key class is
BlowfishKey.
This class should not be instantiated directly, instead use the
java.security.KeyFactory interface.

engineGenerateSecret
protected SecretKey engineGenerateSecret(java.security.spec.KeySpec keySpec)
throws java.security.spec.InvalidKeySpecException
- Generates a Blowfish SecretKey object from the provided key
specification (key material). This class supports the
BlowfishKeySpec and SecretKeySpec KeySpec class.
- Throws:
- java.security.spec.InvalidKeySpecException - The provided KeySpec was not
a BlowfishKeySpec or SecretKeySpec instance.
- Overrides:
- engineGenerateSecret in class SecretKeyFactorySpi
engineGetKeySpec
protected java.security.spec.KeySpec engineGetKeySpec(SecretKey key,
java.lang.Class keySpec)
throws java.security.spec.InvalidKeySpecException
- Returns a specification (key material) of the given key object in
the requested format.
Can convert from an ABA Blowfish Key into a SecretKeySpec or
a BlowfishKeySpec.
- Parameters:
key
- the keykeySpec
- the requested format in which the key material shall
be returned- Throws:
- java.security.spec.InvalidKeySpecException - if the requested key
specification is inappropriate for the given key, or the given
key cannot be dealt with (e.g., the given key has an
unrecognised format).
- Overrides:
- engineGetKeySpec in class SecretKeyFactorySpi
engineTranslateKey
protected SecretKey engineTranslateKey(SecretKey key)
throws java.security.InvalidKeyException
- Translates an Blowfish key object, whose provider may be unknown or
potentially untrusted, into a corresponding key object of this key
factory.
- Parameters:
key
- - the key whose provider is unknown or untrusted- Throws:
- java.security.InvalidKeyException - if the given key cannot be processed
by this key factory.
- Overrides:
- engineTranslateKey in class SecretKeyFactorySpi
