Add author at SFX archive with WinRAR

Question

For example:

In "Autore" i want insert an author.

Answer 1

This dialog shows Authenticode signature information. You'll need to:

1. buy a digital certificate (look specifically for "code signing"),
2. use signtool to add a signature to the .exe file, using your certificate.

Note: I'm not entirely sure if it's compatible with SFX archives. On the one hand, they're just .exe files like any other. But on the other hand, their internal structure is slightly unusual (essentially a stub with a RAR file appended), so it could be that signing may damage the archive. I'll need to research more...

Answer 2

Grawity's answer is the correct way to add an author but signing with signtool seems to corrupt an sfx archive.

I had a 4gb sfx file and after signing it with a certificate the size shrunk to 27mb and it would not extract. With the increasing security of Windows Defender SmartScreen, I don't see a way to share and use an sfx file without a tool like 7-zip.
