Tim Parnell has introduced ExeWrapper, a tool for code signing Windows executables from macOS. 

With it, there’s no need to dual boot into another operating system or deal with VMs to find the one with the right configuration. Cross-platform developers can work, build, and now sign in macOS. 

Adding files to sign is a drag and drop operation. Files can be added statically, or folders can be added to be recursed at sign time. 

ExeWrapper can be downloaded for free from its official website (https://exewrapper.com). It’s capable of code signing free of charge. To sign batches of more than five files a license is needed.
