OutputData Property

The output data.

Syntax

 amazonkms.getOutputData([callback])
 amazonkms.setOutputData( outputData_Buffer, [callback])

Default Value

""

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 getOutputData([callback]) method is defined as:

function(err, buffer){ }

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

'buffer' is the value returned by the method.

The callback for the setOutputData([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

This property is populated with the data that was output from a successful cryptographic operation.

Note: For the Verify operation, this property functions as a secondary input property instead (along with InputData); refer to the Verify method for more information.

Input Sources & Output Destinations

The class automatically determines the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

  1. The InputFile property
  2. The InputData property

The first valid input source found is used. The order in which the output properties are considered is as follows:

  1. The OutputFile property
  2. The OutputData property

This property is not available at design time.

Data Type
