玩坏了！Listary 6.X 注册机

昨晚在论坛上看到一个网友说给Listary写了一个注册机，并且给出了源代码。
虽然他是必备的装机软件之一，但是我之前都没去关注它，因为网上都有现成的注册信息。
看到网友写了两份不同的代码我也就来了点兴趣，看到这东西居然是VB.Net写的而且没加壳，所以就自己用dnspy看了一下相关的反编译代码

这东西的注册码算法真是简单的一批啊。难怪那么容易就被玩坏了。

有了注册码算法，直接刚注册机了。

一、下面是我用rust写的注册机
1.1、添加rand库跟clap库

cargo add rand
cargo add clap

1.2、拷贝下面的代码到main.rs

use rand::Rng;
use clap::{Command, Arg};
 
fn hash1(a: &str) -> u32 {
    let mut num: u32 = 0;
    for c in a.chars() {
        num = num.wrapping_mul(43) + c as u32;
    }
    num
}
 
fn hash2(a: &str) -> u32 {
    let mut num: u32 = 0;
    for c in a.chars() {
        num = (num << 4) + c as u32;
        let num2 = num & 0xF000_0000;
        if num2 != 0 {
            num ^= num2 >> 24;
            num ^= num2;
        }
    }
    num
}
 
fn get_license(email: &str) -> String {
    let alpha_numeric = "23456789ABCDEFGHJKLMNPQRSTUVWXYZ";
    let num = ((hash1(email) as u64) << 32) + hash2(email) as u64;
    let mut license = String::new();
    for i in 0..12 {
        let index = ((num >> (64 - (i + 1) * 5)) & 31) as usize;
        license.push(alpha_numeric.chars().nth(index).unwrap());
    }
    let mut rng = rand::thread_rng();
    let mut text = String::new();
    for i in 0..192 {
        if i == 172 {
            text = format!("{}{}", &text[..160], &license);
        }
        text.push(alpha_numeric.chars().nth(rng.gen_range(0..alpha_numeric.len())).unwrap());
    }
    text
}
 
fn main() {
    let args = Command::new("listary")
        .version("1.0")
        .author("Mr.D <[email protected]>")
        .about("Listary 6.X 注册机")
        .arg(
            Arg::new("email")
                .short('e')
                .long("email")
        )
        .get_matches();

    let email = args.get_one::<String>("email").expect("required");
    println!("{}", listarykeygen::get_license(email));
}

1.3、编译

cargo build

1.4、运行

keygen.exe --email [email protected]
或者
keygen.exe -e [email protected]

二、网友写的C#版注册机

using System;

public class Program {
    private static uint hash1(string a)
    {
        uint num = 0U;
        foreach (char c in a)
        {
            num = 43U * num + (uint)c;
        }
        return num;
    }

    private static uint hash2(string a)
    {
        uint num = 0U;
        foreach (char c in a)
        {
            num = (num << 4) + (uint)c;
            uint num2 = num & 4026531840U;
            if (num2 != 0U)
            {
                num ^= num2 >> 24;
                num ^= num2;
            }
        }
        return num;
    }

    public static string getLicense(string email)
    {
        string ALPHA_NUMERIC = "23456789ABCDEFGHJKLMNPQRSTUVWXYZ";
        ulong num = ((ulong)hash1(email) << 32) + (ulong)hash2(email);
        string license = "";
        for (int i = 0; i < 12; i++)
        {
            int index = (int)(num >> 64 - (i + 1) * 5) & 31;
            license += ALPHA_NUMERIC[index];
        }
        Random random = new Random();
        string text = "";
        for (int i = 0; i < 192; i++)
        {
            if (i == 172)
            {
                text = text.Substring(0, 160) + license;
            }
            text += ALPHA_NUMERIC[random.Next(0, ALPHA_NUMERIC.Length)];
        }
        return text;
    }

    public static void Main()
    {
        string email = "[email protected]";
        string license = getLicense(email);
        Console.WriteLine(license);
    }
}

三、网友写的Python版注册机

3.1、安装numpy库

pip install numpy

3.2、新建一个listarykeygen.py，写入以下代码

import numpy as np
import random

def hash1(a: str) -> np.uint32:
    num = np.uint32(0)
    for c in a:
        num = np.uint32(43) * num + np.uint32(ord(c))
    return num

def hash2(a: str) -> np.uint32:
    num = np.uint32(0)
    for c in a:
        num = (num << np.uint32(4)) + np.uint32(ord(c))
        num2 = num & np.uint32(4026531840)
        if num2 != np.uint32(0):
            num ^= num2 >> np.uint32(24)
            num ^= num2
    return num

def getLicense(email: str) -> str:
    ALPHA_NUMERIC = "23456789ABCDEFGHJKLMNPQRSTUVWXYZ"
    num = np.uint64(hash1(email)) << np.uint64(32) | np.uint64(hash2(email))
    license = ""
    for i in range(12):
        index = int((num >> np.uint64(64 - (i + 1) * 5)) & np.uint64(31))
        license += ALPHA_NUMERIC[index]
    random.seed()
    text = ""
    for i in range(192):
        if i == 172:
            text = text[:160] + license
        text += ALPHA_NUMERIC[np.random.randint(0, len(ALPHA_NUMERIC))]
    return text

email = "[email protected]"
license = getLicense(email)
print(license)

3.3、listarykeygen.py同目录下输入

python listarykeygen.py
