Server Pitches

Thanks @0xTim,

I've checked and resolved Linux issues and pushed a new commit:

  • I've added Linux build in github actions' file
  • RSA-PKCS-1.5 is not supported on linux thus I deactivated all related tests in linux. I think it's negligible as implementation requirement is Recommended-.
  • Converting KeyPath to string using String.init(describing:) is not supported on non-Apple platforms. I've added dynamic member lookup using String.
  • Localization using Bundle.localizing method causes crash probably due to a bug in swift-corelibs-foundation. I've disabled the localization until it got fixed.
