C#实现MD5加密（32位md5加密和16位md5加密）

MD5是经典HASH算法，这里用C#实现一边：

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

namespace ConsoleApp1
{
    class Program
    {
        // 32位md5加密
        public static string GetMD5_32(string s, string _input_charset)
        {
            MD5 md5 = MD5.Create();
            byte[] t = md5.ComputeHash(Encoding.GetEncoding(_input_charset).GetBytes(s));
            StringBuilder stringBuilder = new StringBuilder();
            for (int i = 0; i < t.Length; i++)
            {
                stringBuilder.Append(t[i].ToString("x").PadLeft(2, '0'));
            }
            return stringBuilder.ToString();
        }

        // 16位md5加密
        public static string GetMD5_16(string s)
        {
            MD5 md5 = MD5.Create();
            byte[] t = md5.ComputeHash(UTF8Encoding.Default.GetBytes(s));
            string t2 = BitConverter.ToString(t, 4, 8);
            t2 = t2.Replace("-", "");
            return t2;
        }
        static void Main(string[] args)
        {
            Console.WriteLine(GetMD5_32("123456", "utf-8"));
            Console.WriteLine(GetMD5_16("123456"));
            Console.ReadLine();
        }
    }
}
