Reimplementation of Apple Code Signing and Notarization

Gregory Szorc:

I’m very excited to announce that we now have a pure Rust implementation of a client for Apple’s Notary API in the apple-codesign crate. This means we can now notarize Apple software from any machine where you can get the Rust crate to compile. This means we no longer have a dependency on the 3rd party Apple Transporter application. Notarization, like code signing, is 100% open source Rust code.

[…]

There are probably thousands of companies and individuals who have wanted to release Apple software from non-macOS operating systems. (The existence and popularity of tools like fastlane seems to confirm this.) The historical lack of an Apple code signing and notarization solution that worked outside macOS has prevented this. Well, that barrier has officially fallen.

It’s available here.

Update (2022-08-08): See also: Hacker News.

Apple’s code signing tool is open source, but heavily dependent on Cocoa/OSX libraries like CoreFoundation.
