将Java密码哈希方法翻译为JS实现

Question

我想翻译 Blynk IoT 软件中使用的 Java 代码密码哈希，我可以在 Express.js 应用程序中使用它。谢谢你的帮助！Java代码： https: //www.onlinegdb.com/HJe19lyFBimport 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));    }}目前不起作用的解决方案： https ://repl.it/@patryk0493/blynk-password-hashing

Answer 1

您可以使用标准 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);
