【转载】FInalShell 3.9.4 高级版离线激活

1、激活对话框中任意输入用户名和密码，点离线激活 2、复制机器码至下方代码块中《在此处放置机器码》位置，去掉书名号 3、寻找一个可以在线运行java代码的网站，例如https://www.json.cn/runcode/run_java/

可以在线运行的代码：

import java.io.IOException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Scanner;

class Main{
          
   
    public static void main(String[] args) throws NoSuchAlgorithmException, IOException {
          
   
        System.out.print("请输入FinalShell的离线机器码：");
        @SuppressWarnings("resource")
		//Scanner reader = new Scanner(System.in);
        String machineCode = "cot0@123456789874654512";
        generateKey(machineCode);
    }

    public static void generateKey(String hardwareId) throws NoSuchAlgorithmException {
          
   
        String proKey = transform(61305 + hardwareId + 8552);
        String pfKey = transform(2356 + hardwareId + 13593);
        System.out.println("请将此行复制到离线激活中：" + proKey);
    }

    public static String transform(String str) throws NoSuchAlgorithmException {
          
   

        @SuppressWarnings("unused")
		String md5 = hashMD5(str);

        return hashMD5(str).substring(8, 24);
    }

    public static String hashMD5(String str) throws NoSuchAlgorithmException {
          
   
        MessageDigest digest = MessageDigest.getInstance("MD5");
        byte[] hashed = digest.digest(str.getBytes());
        StringBuilder sb = new StringBuilder();
        for (byte b : hashed) {
          
   
            int len = b & 0xFF;
            if (len < 16) {
          
   
                sb.append("0");
            }
            sb.append(Integer.toHexString(len));
        }
        return sb.toString();
    }
}
