[SOLVED] File Encryption Broken [modified]

[Ben Magee]

Hello, I Am using the following functions to encrypt and decrypt files: Encrypt:

    private void EncryptFile(string inputFile, string outputFile)
    {

        try
        {
            string password = @"19651969"; // Your Key Here
            UnicodeEncoding UE = new UnicodeEncoding();
            byte\[\] key = UE.GetBytes(password);

            string cryptFile = outputFile;
            FileStream fsCrypt = new FileStream(cryptFile, FileMode.Create);

            RijndaelManaged RMCrypto = new RijndaelManaged();

            CryptoStream cs = new CryptoStream(fsCrypt,
                RMCrypto.CreateEncryptor(key, key),
                CryptoStreamMode.Write);

            FileStream fsIn = new FileStream(inputFile, FileMode.Open);

            int data;
            while ((data = fsIn.ReadByte()) != -1)
                cs.WriteByte((byte)data);


            fsIn.Close();
            cs.Close();
            fsCrypt.Close();
        }
        catch
        {
            MessageBox.Show("Encryption failed!", "Error");
        }
    }

Decrypt:

    private void DecryptFile(string inputFile, string outputFile)
    {

        {
            string password = @"19651969"; // Your Key Here

            UnicodeEncoding UE = new UnicodeEncoding();
            byte\[\] key = UE.GetBytes(password);

            FileStream fsCrypt = new FileStream(inputFile, FileMode.Open);

            RijndaelManaged RMCrypto = new RijndaelManaged();

            CryptoStream cs = new CryptoStream(fsCrypt,
                RMCrypto.CreateDecryptor(key, key),
                CryptoStreamMode.Read);

            FileStream fsOut = new FileStream(outputFile, FileMode.Create);

            int data;
            while ((data = cs.ReadByte()) != -1)
                fsOut.WriteByte((byte)data);

            fsOut.Close();
            cs.Close();
            fsCrypt.Close();

        }
    }

I'm using the following code to Decrypt my encrypted file, read it, then encrypt it again.

    private void Form1\_Load(object sender, EventArgs e)
    {       
        
        if (File.Exists("scf.sf"))
        {
            DecryptFile("scf.sf", "sff.sf");
            File.Delete("scf.sf");
            File.Move("sff.sf", "scf.sf");

Oops, My bad, i'd replaced the file so many times in testing I forgot to encrpypt it again :^)
