What would happen if your hardware implemented a ROT13 "engine" as its primary crypto thingie? A responsible approach to crypto should be quite shy. It might drop it's drawers and bare all (source code) but no more. It might show some ankle towards some beefy hardware but only when escorted. A software crypto thingie cannot and should not assume that hardware is trustworthy. However, you can stir some randomness from an untrustworthy source into your entropy pool and not find your knickers around your ankles, if you are careful. Feel free to present your credentials.
