I've been re-reading Through Fiery Trials and I was wondering if it'd be possible to brute force whatever the password it to the 16 petabyte file that holds all the answers,either without electricity,or with it at some future point,using a high-speed computer to crack the password.

The short answer is no.

The longer answer is that to be able to even try to crack it they need to read the encrypted file first which they can't since trying to access it without a password will wipe the memory.

Since it explicitly stated that the file would be erased if brute force was tried (and failed) it is unlikely to be tried except as a last resort.

Answers! I got lots of answers!

A password of only 4 decimal digits would gave you 10000 possible combinations.

A password of 10 decimal digits would gave you 10000000000 combinations.

Considering that password could involve more than digits, and counting just English alphabet (26 letters) and decimal digits we could have a 10-symbol long password with 3656158440062980 combinations.

And we didn't even knew, how exactly the password is composed. It may be any combination of symbols & digits from absolutely any language. For example, let's assume that we have 100-letters long password composed of English (26), Russian (33) and Norway alphabet (29) and 10 decimal digits, counting empty space & a dot. It would be about -

1000000000000000000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000000000000000000
000000000000000000000000000

- combinations.

If you could do a hundred quintillions tries per second, it would took you just about -

3170979198376460000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000000000000000000
000000000000000000000000000000000000

- BILLIONS YEARS, to try them all.

In short: to break the good machine-made password with brute force, you would need more time than Universe existence.

And that also assumes that there isn't some sort of hardware fail-safe, one that allows access to the file from only one access point or location (such as say the temple or the terminal mentioned in the "Vision of Schueler".

Well, how many tries per second the quantum computer could made?

If the device melts down after the third try, the computer's capacity means nothing.

has anyone tried 1 2 3 4 5 6?
