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 keykeySpec
- 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.
