Oh no, crypto backdoors are <i>quite</i> effective at their stated purpose - letting an authority break it when they desire. See also the Clipper chip, DUAL_EC, and so on.<p>The problem is that we&#x27;re no longer talking about physical devices like a gun or a safe, we&#x27;re talking about math. Breaking crypto is basically solving a math problem. If for any reason the problem is solved, it&#x27;s <i>forever</i> solved, and expecting that solution to stay in a few trusted hands against nation-state level actors (or hell, even motivated security professionals) is absurd.<p>The issue here is that the FBI is demanding that Pandora&#x27;s box be opened. There is no closing it again. Are you ready to sacrifice the safety of every iPhone everywhere based on a promise from the FBI?
