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 this 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 method exports the private key of the currently selected Key. The FileName parameter specifies the file on disk that the private key will be written to. The UseAsciiArmor parameter determines whether or not ASCII armoring is used when writing the key to disk.
