Didn’t they try that one already? 🤦♂️
Yeah. It’s ludicrous for two reasons.
1) It’s no exaggeration to say that blocking encrypted traffic would open up catastrophically massive security risks. Fancy doing your online banking over HTTP? Internet shopping?
2) Attempting to ban secure encryption instead would be impossible as the knowledge and technology is in the public domain. If you could somehow remove all the existing tech (and good luck with that), it’d be ten minutes’ work for a competent coder to just rewrite it. It’d be like attempting to ban French.
