UseCNG Property

Whether to use CNG DPAPI.

Syntax

 dpapi.getUseCNG([callback])
 dpapi.setUseCNG( useCNG, [callback])

Default Value

FALSE

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getUseCNG([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setUseCNG([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

The class supports protecting data using either the classic DPAPI or CNG DPAPI implementation. When set to True the CNG DPAPI implementation is sued. When set to False (default) the classic DPAPI implementation is used.
