将Java密码哈希方法转换为JS实现

我想翻译可在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。感谢您的帮助！

Java代码：

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","[email protected]")); 
    }

    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：/@patryk0493/blynk-password-hashing

const btoa = require('btoa');
var util = require('util');
const KJUR = require('jsrsasign');

const password = 'password';
const email = '[email protected]';

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 crypto模块重新实现Java密码哈希：

const crypto = require('crypto');

const hashSalt = (salt) => {
  const hash = crypto.createHash('sha256');
  return hash.update(salt, 'utf8').digest();
}

const password = "password";
const salt = "[email protected]";

const hash = crypto.createHash('sha256');
hash.update(password, 'utf8');
hash.update(hashSalt(salt))

const result = hash.digest('base64');
console.log(result);
