OpenSSL for iOS and Swift the Easy Way

This article explains how to easily integrate OpenSSL into an iOS Swift project for cryptographic tasks like validating Apple app receipt signatures. It compares three methods: building binaries manually, downloading pre-built libraries, and using CocoaPods. The author recommends CocoaPods as the simplest and most maintainable approach, providing step-by-step instructions for installing CocoaPods, creating a Podfile, and running pod install. The focus is on solving the challenge of using OpenSSL's C functions in Swift for PKCS #7 container handling and certificate validation.
