Features

Well, it's actually just one: Generate the pem file for your server.

Check out this gif:

Installation

sudo gem install pem

Make sure, you have the latest version of the Xcode command line tools installed:

xcode-select --install

Usage

pem

Yes, that's the whole command!

This does the following:

Verifies the production push certificate looks alright
Renews the push certificate in case it's necessary
Downloads the certificate
Generates a new .pem file in the current working directory, which you can upload to your server

You can pass parameters like this:

pem -a at.felixkrause.app -u username

If you want to generate a development certificate instead:

pem --development

Environment Variables

In case you prefer environment variables:

PEM_USERNAME
PEM_APP_IDENTIFIER
PEM_CERT_SIGNING_REQUEST in case you want to pass your own signing request file

How does it work?

There are 2 actions involved:

Accessing the iOS Dev Center to download the latest aps_production.cer. See: developer_center.rb.
Generating all the necessary profiles and files to prepare the finished .pem file. See: cert_manager.rb. PEM will create a temporary keychain called PEM.keychain and use that to generate the necessary profiles. That means PEM will not pollute your default keychain.
The .certSigningRequest file will be generated in signing_request.rb

How is my password stored?

PEM uses the password manager from Deliver. Take a look the Deliver README for more information.

Tips

Use the `Provisioning Quicklook plugin`

Download and install the Provisioning Plugin.

It will show you the pem files like this:
