使用CryptoJS使用字节[32]的Sha256？

Question

Using CryptoJS i got as a result a byte[8] when I need a 32 one, this code exactly:

CryptoJS.SHA256(word);

How to get the 32?

Answer 1

This feels a bit convoluted, but I don't have a lot of experience with CryptoJS so perhaps there's a solution that requires less steps:

const CryptoJS = require('crypto-js');

let hash   = CryptoJS.SHA256('hello world');
let buffer = Buffer.from(hash.toString(CryptoJS.enc.Hex), 'hex');
let array  = new Uint8Array(buffer);

If you need a proper JS array (one for which Array.isArray returns true ), you can use this:

let array = Array.from( new Uint8Array(buffer) );

The solution was in my case:

let utf16le = CryptoJS.enc.Utf16LE.parse(word);
let utf16Sha256 = CryptoJS.SHA256(utf16le);
return utf16Sha256.toString(CryptoJS.enc.Hex);

thanks to someone's else question

Answer 3

CryptoJS.SHA256(word).toString()
