Sorry, I didn&#x27;t mean to imply that their ancient OpenSSL doesn&#x27;t do SHA-2, although I had no idea either way. They just say you can&#x27;t use it because it&#x27;s deprecated, and therefore off limits to App Store apps.<p>Historically, I believe the code samples were more or like the ones in the link I posted. I don&#x27;t believe they ever posted anything that showed how to use Security.framework for the heavy lifting. I think they wanted to get everybody to bring their own code to make it so you couldn&#x27;t pirate every app with a patch to one shared library.
