Method Detail

• promptWriteKey

  public final void promptWriteKey(PromptingKeyProvider.Controller<AesCipherParameters> controller)

  Description copied from interface: PromptingKeyProvider.View
  Prompts the user for the key for (over)writing the contents of a new or existing protected resource. Upon return, the implementation should have updated the key property of the given controller.

  If the implementation has called PromptingKeyProvider.Controller.setKey(K) with a non-null parameter, then a clone of this object will be used as the key.

  Otherwise, prompting for a key is permanently disabled and each subsequent call to SafeKeyProvider.getWriteKey() or SafeKeyProvider.getReadKey(boolean) results in a KeyPromptingCancelledException until PromptingKeyProvider.resetCancelledKey() or PromptingKeyProvider.resetUnconditionally() gets called.

  Specified by:

  promptWriteKey in interface PromptingKeyProvider.View<AesCipherParameters>

  Parameters:

  controller - The key controller for storing the result.

• promptReadKey

  public void promptReadKey(PromptingKeyProvider.Controller<AesCipherParameters> controller,
                   boolean invalid)

  Description copied from interface: PromptingKeyProvider.View
  Prompts the user for the key for reading the contents of an existing protected resource. Upon return, the implementation should have updated the key property of the given controller.

  If the implementation has called PromptingKeyProvider.Controller.setKey(K) with a non-null parameter, then a clone of this object will be used as the key.

  Otherwise, if the implementation has called PromptingKeyProvider.Controller.setKey(K) with a null parameter or throws a KeyPromptingCancelledException, then prompting for the key is permanently disabled and each subsequent call to SafeKeyProvider.getWriteKey() or SafeKeyProvider.getReadKey(boolean) results in a KeyPromptingCancelledException until PromptingKeyProvider.resetCancelledKey() or PromptingKeyProvider.resetUnconditionally() gets called.

  Otherwise, the state of the key provider is not changed and this method gets called again.

  Specified by:

  promptReadKey in interface PromptingKeyProvider.View<AesCipherParameters>

  Parameters:

  controller - The key controller for storing the result.

  invalid - true iff a previous call to this method resulted in an invalid key.
