Upgrade Method
Upgrades existing XAdES signature to a new form.
Syntax
xadessigner.upgrade(toForm, [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
XAdES standard defines a number of different 'forms' of signatures which can be used for different purposes. Use this method to upgrade XAdES signature to a new form specified by ToForm. Signatures can normally be upgraded from less sophisticated levels (BES, EPES) to more sophisticated (T, C, X, X-L, A).
