code signing support

[Jonas Heinrich]

Hey,
thanks for this great tool. It is already very helpful in the development and publishing process.
In an older blog post you wrote that you planned to support code-signing in krankerl but had issues with the json implementation. Code signing would be a really good feature otherwise I have to install several dependencies in my Gitlab CI config.

I guess the manual process looks something like this:

• krankerl package
• download & install php and occ (nextcloud)
• uncompress build package to a temporary directory
• sign code using occ
• recompress temporary directory and put archive back into build/artifacts directory
• krankerl publish

Best regards
Jonas

Hi @onny,

it was indeed on my todo. The main issue was (is?) that Nextcloud uses the non-interoperable PHP json serializer and then signs this string. This method isn't trivial to reproduce with Rust. But I remember that I also discussed this with @rullzer and we wanted to change the signature format for this.

Another possible idea is to run the json serialization through php, like generate a tiny php script and run that through the php interpreter from Rust. That should give the same result.
