(AutoIt) Create ITIDA Signed JSON and Send to ETA (Egypt Tax Authority) PortalSee more Egypt ITIDA ExamplesDemonstrates how to create a .p7s signature that fits Egypt's ITIDA requirements where Chilkat automatically does the ITIDA JSON canonicalization. Also shows the code to send to the ETA Portal.
