engineGenerateSecret
- protected javax.crypto.SecretKey engineGenerateSecret( java.security.spec.KeySpec keySpec)
- throws java.security.spec.InvalidKeySpecException
Generates a
SecretKey
object from the provided key
specification (key material).
Specified by:
engineGenerateSecret
in 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 key factory to produce a public key. FIPSRuntimeException
- if SelfTest.isFipsRunnable returns false. internalGenerateSecret
- protected javax.crypto.SecretKey internalGenerateSecret( java.security.spec.KeySpec keySpec)
- throws java.security.spec.InvalidKeySpecException
Generates a
SecretKey
object from the provided key
specification (key material).
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 key factory to produce a public key. engineGetKeySpec
- protected java.security.spec.KeySpec engineGetKeySpec( javax.crypto.SecretKey key,
- java.lang.Class keySpec)
- throws java.security.spec.InvalidKeySpecException
Returns a specification (key material) of the given key
in the requested format.
Specified by:
engineGetKeySpec
in 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, or the given key cannot be processed
(e.g., the given key has an unrecognized algorithm or format). FIPSRuntimeException
- if SelfTest.isFipsRunnable returns false. internalGetKeySpec
- protected java.security.spec.KeySpec internalGetKeySpec( javax.crypto.SecretKey key,
- java.lang.Class keySpec)
- throws java.security.spec.InvalidKeySpecException
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:
java.security.spec.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 javax.crypto.SecretKey engineTranslateKey( javax.crypto.SecretKey key)
- throws java.security.InvalidKeyException
This action is not allowed in this provider. This method is only
here to be complient wiht the SUN JCE JCK tests. If a key is passed in,
this method will basically return it back to you without doing any work.
Specified by:
engineTranslateKey
in class javax.crypto.SecretKeyFactorySpi
Parameters:
key
- the key. Throws:
java.security.InvalidKeyException
- if the given key is null.
