[BUG] Critical bug after file saving

[Sigmanor]

Sometimes after saving the file, there is no possibility to open it anymore, the password is incorrect.
This bug only appears in 1.1.3+ versions.

@h5p9sl can you help me to fix this? Because on version 1.1.2 I can't reproduce this bug, so it's appeared after the last updates, and I have not changed anything in the encryption code in recent updates. So I need your help.

To catch this bug I wrote a small code. This code is try to encrypt the opened file, and then decrypt it.

Loop that saving the file for a 10 times

            int i = 1;
            while (i != 10)
            {
                i++;
                Text = i.ToString();
                saveToolStripMenuItem1_Click_1(sender, e);
                CheckFileSavedCorrectly();
            }

This code is for open the file after saving

private void CheckFileSavedCorrectly()
        {
            string de = "";
            try
            {
                string opnfile = File.ReadAllText(OpenFile.FileName);
                de = AES.Decrypt(opnfile, PublicVar.encryptionKey.Get(), null, ps.HashAlgorithm, ps.PasswordIterations, ps.KeySize);
                customRTB.Text = de;
                string cc2 = customRTB.Text.Length.ToString(CultureInfo.InvariantCulture);
                customRTB.Select(Convert.ToInt32(cc2), 0);
            }
            catch (CryptographicException)
            {
                MessageBox.Show("Gotcha!");
            }

        }

How it works
