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