I have a certificate for code signing and I want to know if is there a standard way to sign and verify a nodejs/javascript code? Maybe using OpenSSL or other tools?
Unlike binaries, the nodejs/javascript code has multiples files and that makes it more complex to use some utilities to sign software.
If you upload JavaScript to a web server, you "sign" it by serving it with a TLS certificate. You can use Let's Encrypt to get one for free.
If you're trying to, essentially credit yourself, adding a license alongside your JavaScript files is how you would "sign" it.
Since JavaScript is not a binary format itself, there's no way to sign it with a Code Signing Certificate. However, Node.js is a signed binary that is used to execute your code.
If you're trying to sign a binary compiled from JavaScript with a tool like pkg, use a Code Signing Certificate.
