将 Java 密码哈希方法转化为 JS 实现

Question

我想翻译我可以在 Express.js 应用程序中使用的 Blynk IoT 软件中使用的 Java 代码密码哈希。谢谢你的帮助！

Java代码：https : //www.onlinegdb.com/HJe19lyFB

import java.nio.charset.StandardCharsets;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.util.Base64;

public class Main {

    public static void main(String[] args){

        System.out.println(makeHash("password","[e-mail]")); 

    }

    private static final String SHA_256 = "SHA-256";

    private Main() {

        try {

            MessageDigest.getInstance(SHA_256);

        } catch (NoSuchAlgorithmException e) {

        }

    }

    public static String makeHash(String password, String salt) {

        try {

            MessageDigest md = MessageDigest.getInstance(SHA_256);

            md.update(password.getBytes(StandardCharsets.UTF_8));

            byte[] byteData = md.digest(makeHash(salt.toLowerCase()));

            return Base64.getEncoder().encodeToString(byteData);

        } catch (Exception e) {

            //ignore, will never happen.

        }

        return password;

    }

    private static byte[] makeHash(String val) throws NoSuchAlgorithmException {

        return MessageDigest.getInstance(SHA_256).digest(val.getBytes(StandardCharsets.UTF_8));

    }

}

当前不起作用的解决方案：https : //repl.it/@patryk0493/blynk-password-hashing

const btoa = require('btoa');

var util = require('util');

const KJUR = require('jsrsasign');

const password = 'password';

const email = '[e-mail]';

const options = {"alg": "sha256", "prov": "cryptojs"}

makeHash = (str) => {

  const md = new KJUR.crypto.MessageDigest(options);

  return md.digestString(new util.TextEncoder().encode(str.toLowerCase()))

}

const md = new KJUR.crypto.MessageDigest(options);

md.updateString(new util.TextEncoder().encode(password));

const byteData = md.digest(makeHash(email.toLowerCase()));

const base64 = btoa(byteData)

console.log(base64);

您可以使用标准的 Node.js加密模块重新实现 Java 密码哈希：const crypto = require('crypto');const makeHash = (data) => {  const hash = crypto.createHash('sha256');  return hash.update(data, 'utf8');}const password = "password";const salt = "[e-mail]";const result = makeHash(password)  .update(makeHash(salt).digest())  .digest('base64')console.log(result);
