SignIt

SignIt is a simple to use Windows software to digitally sign your EXE files. SignIt requires a Digital Code Signing Certificate private keyfile.  Before using this software, you must purchase a Code Signing Certificate from companies like Sectigo, Thawte, etc.  After installing the certificate and installing Signtool, part of the Windows SDK, you're ready to use SignIt.
 One feature that makes this utility nice, you setup project files and it stores your project files for next use.   So, if you need to digitally sign a new release or update an existing file, load the project and run to sign, it's that easy!
