嗨即时通讯使用C＃和我制作加密器/解密器和我的解密按钮不起作用它启动正常，但当我点击按钮似乎没有发生帮助 [英] Hi im using C# and im making a encryptor/decryptor and my decrypt button doesnt work it starts up fine but when I click the button nothing seems to happen help

问题描述

这是我的代码按钮2无效但在启动时出现

this is my code button 2 doesnt work but appears when it starts

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Security.Cryptography;

namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        byte[] encrypted;
        private void button1_Click(object sender, EventArgs e)
        {
            TripleDESCryptoServiceProvider triple = new TripleDESCryptoServiceProvider();
            UTF8Encoding u = new UTF8Encoding();
            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            triple.Key = md5.ComputeHash(u.GetBytes(textBox1.Text));
            triple.Mode = CipherMode.ECB;
            triple.Padding = PaddingMode.PKCS7;
            ICryptoTransform trans = triple.CreateEncryptor();
            encrypted = trans.TransformFinalBlock(u.GetBytes(textBox2.Text), 0, u.GetBytes(textBox2.Text).Length);
            textBox3.Text = BitConverter.ToString(encrypted);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            TripleDESCryptoServiceProvider triple = new TripleDESCryptoServiceProvider();
            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            UTF8Encoding u = new UTF8Encoding();
            triple.Key = md5.ComputeHash(u.GetBytes(textBox1.Text));
            triple.Mode = CipherMode.ECB;
            triple.Padding = PaddingMode.PKCS7;
            ICryptoTransform trans = triple.CreateDecryptor();
            textBox5.Text = u.GetString(trans.TransformFinalBlock(encrypted, 0, encrypted.Length));
        }
    }
}

我尝试了什么：



很多东西我试过但没有结果

many things i have tried but no result

推荐答案

请参阅以下MSDN文章。它有一个使用Triple DES加密加密和解密的示例 - 它是一个命令行应用程序，但您应该能够根据需要进行编辑。



Rfc2898DeriveBytes Class（System.Security.Cryptography） [ ^ ]



亲切的问候

Refer the following MSDN article. It has an example that encrypts and decrypts using Triple DES encryption - it is a command line application but you should be able to edit as required.

Rfc2898DeriveBytes Class (System.Security.Cryptography)[^]

Kind Regards

可以使用更新的哈希函数，例如安全哈希算法SHA-256和SHA-512。考虑使用SHA256类或SHA512类而不是MD5CryptoServiceProvider类。仅使用MD5CryptoServiceProvider与遗留应用程序和数据兼容。

Newer hash functions such as the Secure Hash Algorithms SHA-256 and SHA-512 are available. Consider using the SHA256 class or the SHA512 class instead of the MD5CryptoServiceProvider class. Use MD5CryptoServiceProvider only for compatibility with legacy applications and data.
