@julian, I believe Ricky had wrapped classes from the system.security namespace.

Here’s a little something for ya .. it’ll serialize an object to xml, encrypt it, and save it as a file.

public void SaveToFile(string Path) { byte[] data;


            using (MemoryStream ms = new MemoryStream())

            {

                XmlSerializer serializer = new XmlSerializer(typeof(List));

                serializer.Serialize(ms, this.Soldiers);
                data = ReadByteArrayFromInputStream(ms);

                ms.Close();

            }
            using (FileStream fs = File.Create(Path))

            {

                Aes aes = Aes.Create();

                using (CryptoStream cs = new CryptoStream(

                    fs,

                    aes.CreateEncryptor(GetKey(), GetIV()),

                    CryptoStreamMode.Write))

                {

                    cs.Write(data, 0, data.Length);

cs.Close(); } fs.Close(); } }
