      Apple: “Building a version of iOS that bypasses security in this way would undeniably create a backdoor. And while the government may argue that its use would be limited to this case, there is no way to guarantee such control.” https://www.apple.com/customer-letter/ …pic.twitter.com/eAyWx3pxA0

      Maybe I'm missing something, but it sounds like Apple is saying that the only thing preventing third parties from decrypting data currently on iOS phones is them? Doesn't that mean Apple already "has" a de-facto backdoor, but they aren't using it? Isn't this "bad" encryption?

      IIRC, the answer was, at least at that time, "yes". Since the "pins" necessary to unlock phones were often quite short (like 4 digits), a brute-force attack was probably trivial. The FBI, for some reason, thought they needed to ask Apple to help them with this?

      But the only reason they would need Apple's help is if they just had no idea what they were doing. One would assume a black hat would be able to just do the brute-force attack by having disassembled Apple's OS code, know how the key generation works, and then run it.

          The FBI was just asking Apple to provide them with that (the thing that allows them to generate keys from pins and then check them against the encrypted data to see if they work).

          That was my recollection anyway!
