Cryptographically secure array shuffle

QUESTION

Cryptographically secure array shuffle

Asked 2018-Apr-27 at 17:55

I am trying to shuffle an array using a cryptographically secure source of entropy.

I found a similar question, regarding shuffling arrays here How to randomize (shuffle) a JavaScript array?. However almost all solutions make use of Math.random, which is not secure. Unfortunately I do not have the reputation to comment/post on that question.

Here is the solution I came up with, which uses Durstenfeld shuffling paired with a CSPRNG for generating random integers in a given range (provided by random-number-csprng lib).

ANSWER

Answered 2018-Apr-27 at 17:55

After reviewing extensively, I have concluded that the solution is correct, being a verbatim implementation of the Durstenfeld shuffle.

However, the Durstenfeld / Fisher-Yates shuffle is only as random as it's RNG source. My solution depends on the random-number-csprng CSPRNG lib, which uses crypto.randomBytesAsync, and is therefore cryptographically secure for most all purposes (see How random is crypto#randomBytes?).

UPDATE: I have published a functionally equivalent yet more efficient version of this solution here crypto-secure-shuffle, also available as an npm package. Here is the relevant implementation:
