C#实现MD5加密

C#实现MD5加密。

1、创建MD5Str.cs加密处理类

 

public class MD5Str
{
    /// <summary>
    /// 字符串MD5加密
    /// </summary>
    /// <param name="Text">要加密的字符串</param>
    /// <returns>密文</returns>
    public static string MD5(string Text)
    {
        byte[] buffer = System.Text.Encoding.Default.GetBytes(Text);
        try
        {
            System.Security.Cryptography.MD5CryptoServiceProvider check;
            check = new System.Security.Cryptography.MD5CryptoServiceProvider();
            byte[] somme = check.ComputeHash(buffer);
            string ret = "";
            foreach (byte a in somme)
            {
                if (a < 16)
                    ret += "0" + a.ToString("X");
                else
                    ret += a.ToString("X");
            }
            return ret.ToLower();
        }
        catch
        {
            throw;
        }
    }
}

 

2、运行测试

 

static void Main(string[] args)
{
    string data = "123456789";  //要加密的数据
    string encodeStr = "";   //加密后文本

    encodeStr = MD5Str.MD5(data);

    Console.WriteLine("原文本：{0}", data);
    Console.WriteLine("加密后文本：{0}", encodeStr);
    Console.Read();
}
