SignFile Method

Signs a file.

Syntax

publickeycrypto.signFile(sourceFile, destFile, detached, [callback])

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

Use this method to sign a file and save the protected message to another file.

Specify the signing key in Key property before the signing. Please make sure the assigned key has a private key associated with it.

Set Detached parameter to false to create an enveloped/enveloping signature. This maynot be supported by certain algorithms or encryption modes.
