C#中使用SHA1和MD5加密字符串

SHA1和MD5加密均为不可逆加密。代码如下：

using System.Security.Cryptography;  //添加Using
 
static void Main(string[] args)
        {
            string password = "";
 
            //SHA1加密方法
            var sha1 = new SHA1CryptoServiceProvider();
            byte[] str01 = Encoding.Default.GetBytes(password);
            byte[] str02 = sha1.ComputeHash(str01);
            var result = BitConverter.ToString(str02).Replace("-", "");
 
            //MD5加密方法
            var md5 = new MD5CryptoServiceProvider();
            byte[] str1 = Encoding.Default.GetBytes(password);
            byte[] str2 = md5.ComputeHash(str1);
            var rethash = BitConverter.ToString(str2).Replace("-", "");
 
            Console.WriteLine(rethash);
            Console.WriteLine(result);
            Console.Read();
        }
