Función MD5

Dejo la función para realizar el Hash MD5:

public string md5(string password)
{
  System.Security.Cryptography.MD5 md5;
  md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
  Byte[] encodedBytes = md5.ComputeHash(ASCIIEncoding.Default.GetBytes(password));
  return  System.Text.RegularExpressions.Regex.Replace(BitConverter.ToString(encodedBytes).ToLower(), @"-", "");
}
