secure-shuffle

Shuffle an array using secure-random-uniform as the RNG

Install

npm install secure-shuffle

Usage

Note that this module mutates the passed array, as you can always .slice(0) to get a "cheap" copy:

const sshuffle = require('secure-shuffle')
 
const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9]
 
const sarr = sshuffle(arr.slice(0)) // sarr is now a shuffled copy of arr
 
sshuffle(arr) // arr is now shuffled

API

secureShuffle(arr)

Takes an array-like structure (eg. Buffer) and shuffles it. Note that the original will be mutated for performance reasons. You might want to copy the structure before passing it, depending on your use-case.

As a convenience, the passed structure will be returned.
