File integrity and Digital code signing
We are using a code signing certificate from Comodo.
The EXE files are signed using Microsoft Authenticode technology.
In order to check file integrity and authenticity, download it first (don’t open it), then
in Windows Explorer right-click on the file and select Properties. Check under “Digital Signatures”
to verify that the name of the signer is 128 Consulting. If you use Windows XP, SP2 or later,
you will be presented with the signature automatically once the executable is started.
