Code Sign Windows programs with Apple Certificate?

Had the same idea some time ago. But I don't think it's possible, because the Apple Developer Certificate is verified (signed) by Apple and I don't think that the Apple Root Certificate is installed on average Windows machines.

Here is a detailed article about it: http://luminaryapps.com/blog/code-signing-and-packaging-windows-apps-on-a-mac/ and more generally about code-signing Windows apps on a Mac. I quote:

Now you need to get a Windows developer certificate. Unfortunately you can't use your Apple certificate (well, actually you can, but it doesn't help because Apple isn't a certificate authority that Windows recognizes). Here is a list of root certificate authorities recognized by Windows.

So this seems to confirm the other answers.

Hi Joe LTNS I check the status of this question every time my Comodo CS certificate comes up for renewal, because hassle/money vs Apple's

Alas, Apple's CA still not in Windows golden list AFAIK. I checked Apple Software Update under Win10 and its cert issuer is Verisign.

OT Not a cert expert here, but if Apple concocted an intermediate cert that both the CA and Apple could vouch/revoke, not a few Windows devs would pony up for Apple's $100 Dev program for that su-weet 5 year non-MAS codesign cert (and probably dabble in App Store/ios development as a bonus)
