Yeah, I'm not sure why 7-zip is still unsigned. Code signing certificates are cheaper now and it's much easier to check that than random hashes, not to mention reputation trusting by AVs and such.
Fuck that. 7-zip.org has official download links - you can expect those to be the official binaries from 7-zip.org - and a code sigining certificate won't really tell you more than that.
If you want Microsoft to gatekeep your software then please complain to Microsoft if that inconveniences you, not to anyone else.

Have you heard of compromised download servers? At least signing it on your machine before distribution means you can guarantee it hasn’t changed. (And yes, you can just change the hash on the website, it’s the same server)
It still won't guarantee you get to skip the bad smartscreen prompt, though.
And it won't instantly skip SmartScreen (that requires EV which is $300+) but it helps to establish reputation, i.e.: if you consistently release safe software signed with a cert named X, then SmartScreen and co. learn to give a good starting reputation to binaries signed by X.
> The Linux Foundation, Red Hat, Google, and Purdue have unveiled the free 'sigstore' service that lets developers code-sign and verify open source software to prevent supply-chain attacks.
> As demonstrated by the recent dependency confusion attacks and malicious typo-squatted NPM packages, the open-source ecosystem is commonly targeted for supply-chain attacks.
> To pull these attacks off, threat actors will create malicious open-source packages and upload them to public repositories using names similar to popular legitimate packages. If a developer mistakenly includes the malicious package in their own project, malicious code will automatically be executed when the project is built.
> To prevent these types of attacks, 'sigstore' will be a free-to-use non-profit software signing service that allows developers to sign open-source software and verify their authenticity.

Not available to us plebs and vague enough that it isn't even clear if they provide Windows-compatible code signing certs.
