If smartphones can wipe themselves irrecoverably on factory reset by simply throwing away the storage encryption key, why not do the same thing and avoid all the trouble? Surely erasing 512 bits or so, irrecoverably, can be done quickly.

- MattPalmer1086 1y agoSymmetric encryption, used for data storage only loses about half its key strength to a quantum computer, due to Grover's algorithm. So if you are using a 256 bit key you're still fine. Even a 128 bit key would still have 64 bit strength, which would still be a huge amount of work to crack, even though theoretically possible.
