Digital signature is a specific code provided by secure messenger that signifies that the information you are transmitting is safe and unalterable. The digital signature is usually visible to the outside world, but will remain within the memory of your device, forever. The latest version, Secure Messenger v4, which came into effect on the 3rd of March 2010, is freely downloadable from the manufacturer’s official website.
