title: Is it possible to create the certificate to sign Apple Wallet Passes from a non-iOS system such as Ubuntu?
body: <p>I'd like to create a certificate from Apple developer account and use it to sign Apple Wallet passes / passbook. So I can implement a server to generate the wallet passes to serve up my mobile app. </p>
  
  <p>The challenge to me is I'm on linux (Ubuntu to be specific). There are a bunch of npm modules as far as I can see, that can be used to implement a server to generate the pass but the first step is to create a certificate from Apple. So my question is it seems to me that is not even possible without a Mac? Does anyone know if it is even possible to create that certificate from a linux machine like Ubuntu? </p>
  
  <p>Thanks</p>
