CanSign Property

Returns true if the crypto object is capable of data signing.

Syntax

 publickeycrypto.getCanSign([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 getCanSign([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 setCanSign([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 returns true if the crypto object can be used for signing data and validating signatures. This capability depends on the cryptographic algorithm.

This property is read-only and not available at design time.

Data Type

Boolean
