            RNGCryptoServiceProvider crypto = new RNGCryptoServiceProvider();

            crypto.GetNonZeroBytes(data);

            data = new byte[maxSize];

            crypto.GetNonZeroBytes(data);

            StringBuilder result = new StringBuilder(maxSize);

            foreach (byte b in data)

            {

                result.Append(chars[b % (chars.Length)]);

            }

            return result.ToString();

        }
