Constructor Summary
`protected` | `JCESecretKeyFactory(java.lang.String algName)`

Method Summary
`protected SecretKey` | `engineGenerateSecret(java.security.spec.KeySpec keySpec)` Generates a `SecretKey` object from the provided key specification (key material).
`protected java.security.spec.KeySpec` | `engineGetKeySpec(SecretKey key, java.lang.Class keySpec)` Returns a specification (key material) of the given key object in the requested format.
`protected SecretKey` | `engineTranslateKey(SecretKey key)` Translates a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this secret-key factory.

Constructor Detail

### JCESecretKeyFactory

    protected JCESecretKeyFactory(java.lang.String algName)

Method Detail

### 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 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 (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.
