how to add openssl to a swift project - swift

Question

I am learning how to add in-app purchase receipt validation to my iOS/OSX projects.
There is a nice overview here and the WWDC14 has good videos on this topic.
Plenty of sample code, but everyone skips one step. How to import the openSSL header. The swift compiler complains that there is no such module.
import Foundation
import StoreKit
import openssl //no such module ???
I am already stuck before writing one line of code. Where is the openssl framework hiding?

There is no OpenSSL module built in. You have to compile it yourself - this is for security so that everyone doesn't implement the exact same security.
Take a look at :

There is a also a cocoapods at http://cocoapods.org/?q=openssl
You should never use a static module provided by someone else. Always build your own.
