Safari Tests 'Not Secure' Warning For Unencrypted Websites (cnet.com)
Similar to Chrome, Apple's Safari browser is testing a warning system for when users visit websites that aren't protected by HTTPS encryption. "The feature for now is only in Safari Technology Preview 70, a version of the web browser Apple uses to test technology it typically brings to the ordinary version of Safari," reports CNET. From the report: Apple didn't immediately respond to a request for comment on its plans for bringing the warning to mainstream Safari. Apple's browser does warn you already if you have an insecure connection to a very sensitive website for typing in passwords or credit card numbers.
So what you’re saying is that we need content validation without full encryption for most things. This is how windows update (and I think apple update). Hashes of the packages are transferred securely, while the bulk data is in the clear. This allows the data to be verified, while still permitting caching to work.
