using System;

using System.Linq;
using System.Text;

namespace ConsoleApplication1 {
    class Program {
        public static string md5(string input) {
            // step 1, calculate MD5 hash from input
            var md5 = System.Security.Cryptography.MD5.Create();
            var inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
            var hash = md5.ComputeHash(inputBytes);

            // step 2, convert byte array to hex string
            var sb = new StringBuilder();
            foreach (var b in hash) {
                sb.Append(b.ToString("x2"));
            }
            return sb.ToString();
        }

        static void Main(string[] args) {
            Console.WriteLine(md5("hello"));
            Console.ReadKey();
        }
    }
