    Because they would have to possess technology that doesn’t exist in order to circumvent actual encryption without a key.

    If I adequately encrypt my own data, and keep the keys a secret, I could hand my hard drive off to Microsoft and they could spend billions running all their AI clusters trying to crack it, and it would be a futile endeavor.

    If the government had the technology to bypass encryption or quickly and inexpensively crack it, they’d use it for a whole lot more than unlocking smartphones. They could basically control the flow of Bitcoin on a whim with such tech.

      I am aware that there are secure encryptions, but android isn’t hardware encrypted isn’t it? Haven’t used google android for a while, but no encryption was one of the reasons I moved away from it.

      No idea about apple, but longer startup times for storage encryption doesn’t seem like a very apple thing to do

      Also phones are so seldom turned off, and if the system is running storage encryption becomes less of a concern as the key is somewhere in the ram

        For a few years now Android has been encrypting storage. Not the SD card, and maybe not even the internal storage (which on android land means your files that you can access with a file manager without root) but I’m not sure about that part. The app’s main data is surely encrypted though, when the security menu in the settings says so.

        But, there’s a loophole. Or two.
        The parent commenter said, actual encryption can’t be broken without keys.
        First, the keys are in the black box TPM of the phone.
        Second, how do you verify that the phone uses an effective and unmodified encryption algorithm, and also that keys are never leaked anywhere?
        And now consider that popular brands have been bundling malware for years, some of which cannot really be uninstalled either.

          Yeah TPM chip encryption is mostly not secure (at least not by simply existing, as an encryption with with a strong password that only exists in your head is) I’ve seen a german youtuber crack the bitlocker TPM encryption of a windows think pad, I have no doubt big companies can do this for the 3-4 most used TPM chips in android phones

          And if you got the device and can damage it, even if you couldn’t crack the chip, putting the silicia under an electron microscope is always an option (lots of actual manhours of actual experts needed, but you could charge the client heavily to compensate)

            No. The TPM was not cracked. The communication was sniffed, which is unencrypted. This requires a Device to be modified and then successfully unlocked to get exploited also this does not affect devices where the tpm is integrated in the SoC.
