HMACKey Property

The HMAC key used with the 'HMAC-SHA1' signing algorithm.

Syntax

 xmlsig.getHMACKey([callback])
 xmlsig.setHMACKey( HMACKey_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 getHMACKey([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 setHMACKey([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 defines the HMAC key to be used when SigningAlgorithm is set to "HMAC-SHA1". This must be set before calling before calling Sign.

This property is also applicable when calling VerifySignature. This may be set before calling VerifySignature or from within the SignatureInfo event.

This property is not available at design time.
