Web开发：MD5加密的demo

可直接在控制台程序运行：

using System;
using System.Security.Cryptography;
using System.Text;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {

            string input = "123456";//请输入要加密的字符串

            string encryptedString = GetMd5Hash(input);

            Console.WriteLine("加密后的字符串为：" + encryptedString);

            Console.ReadKey();
        }

        // 计算字符串的 MD5 哈希值
        static string GetMd5Hash(string input)
        {
            using (MD5 md5Hash = MD5.Create())
            {
                byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));

                StringBuilder builder = new StringBuilder();

                for (int i = 0; i < data.Length; i++)
                {
                    builder.Append(data[i].ToString("x2"));
                }

                return builder.ToString();
            }
        }
    }
}
