Issue Making .PEM file for other language
===

Hello Friends,
               I have to need To Make a PEM format File for push notification for server. but my web service is from .net.I read the tutorial of Raywenderlich.and follow it. But there are that lines confused me.

"The specifics of what PEM is doesn’t really matter (in fact, I have no idea) but it makes it easier for PHP to use our certificate. If you write your push server in another language, these following steps may not apply to you."

i arises some quiz.

is those process for make PEM file in this tutorial is not correct for .net?
is it only work for PHP?

the link is that tutorial is: http://www.raywenderlich.com/3443/apple-push-notification-services-tutorial-part-12

please help me . Thanks in advance :)
