I think I read that it takes 80ms just to run the decryption algorithm on the iPhone, so while having unlimited retries would get them in eventually it will not speed up the brute force attack.
- jontas 11y agoAssuming it is a 4 digit numeric passcode, that's only 10,000 possible combinations. At 80ms each (let's round up to 100ms to be conservative) that's only ~17 minutes. Even if it is a 6 digit pin we're only talking about ~28 hours (if they use a single, serial process).
- habosa 11y agoThat is true. Most people use a 4-digit or 6-digit numeric password and that's what the FBI is betting on when they ask to remove the brute force restrictions. However Apple allows something like a 35-char max with numbers and letters so in the worst case they will never crack it.
- jontas 11y agoI don't know if it is correct but I've seen it mentioned elsewhere in this thread that the passcode they need is 4 digits.
