Very interesting. I’ve been writing code for a while but if I’m honest I have no idea how code signing works. Any good resource on how it works especially in php?

It's just an Ed25519 signature of a file. The closest thing we have to runtime code-signing are Phar signatures. https://www.php.net/manual/en/phar.fileformat.signature.php
