The code for generating a HASH is:

using System.Security.Cryptography;
using System.Text;
protected static String GetHash(String plainString)
    byte[] toBeHashed = System.Text.Encoding.UTF8.GetBytes(plainString);
    MD5CryptoServiceProvider cryptHandler = new MD5CryptoServiceProvider();
    byte[] hash = cryptHandler.ComputeHash(toBeHashed);
    String hashed = "";
    foreach (byte i in hash)
        if (i < 16)
            hashed += "0" + i.ToString("x");
            hashed += i.ToString("x");
    return hashed;
