c++ - Converting QString/QChar to be accepted with Crypto++ -


I want to create a program that encrypts (later decrypts) user input string is the beginning for encryption here: 

  QString getData = ui- & gt; Text-> ToPlainText (); // std :: string data to process output; // result will be 32 encoded string, so std :: string is ok.

Now, I have to convert from QString to char * or std :: string crypto + + I would have thought that QByteArray would be okay because it has the .data () function, which gives char * . ( getData is always 17 or more bytes long: Crypto PP requires at least 17 bytes for AES encryption). Therefore, I have used the following code: 

  QByteArray data; Data.append (GetData); // Make AES encryptor: // Encrypting AES and Base32: CryptoPP :: StringSource SS ((byte * constant) data.data (), data.size (), true, new CryptoPP: : StreamTransformationFilter (Encryptor, New CryptoPP :: Base32Encoder (New CryptoPP :: StringSink (Production)) // Base32Encoder) // StreamTransformationFilter); // string source UI-> Text-> clear (); GetData = output.c_str (); UI- & gt; Text & gt; SetText (GetData);

Everything looks fine. But I want to support it non-ASCII characters (I mean Russian, etc.). After decryption they are ? . How can I fix this? I understand that std :: string doesn`t support them

edit:. Code is updated here:

Encryption:

QString getData = ui- & gt; Text-> ToPlainText (); // std :: string data to process output; QByteArray Data = getData.toUtf8 (); // Creating keys and iv: & lt; .. & gt; // Creating AES Encryption: & lt; .. & gt; // Encrypting AES and Base32: CryptoPP :: StringSource SS ((byte constant) data.data (), getData.size () * 2, true, new CryptoPP :: StreamTransformationFilter (Encryptor, New CryptoPP :: Base32Encoder ( New CryptoPP :: String Sync (Output)) // Base 32 Encoder) // Stream Transformation Filter;); // string source UI-> Text-> clear (); GetData = output.c_str (); UI- & gt; Text & gt; SetText (GetData);

and decryption: 

  QString getData = ui- & gt; Text-> ToPlainText (); QByteArray data; Data.append (GetData); Std :: string output; // Key Creation and iv: Byte Key [Crypopp :: AES :: DFFLBECNHNGHAD], iv [crypopp :: AES :: Blockscage]; // Making them brain: (Requires randomization): MEMSet (key, 0x01, crypopp :: AES :: DEFLBEKENNGH); :: MEMSet (iv, 0x01, crypopp :: AES :: Blocksseed); // create AES decryptor: CryptoPP :: CBC_Mode & LT; CryptoPP :: AES & gt; :: decryption decryptor (key, sizeof (key), iv); // Decrypting Base32 and AES CryptoPP :: StringSource SS ((constant byte *) data.data (), data.size (), true, new CryptoPP :: Base32Decoder (New CryptoPP :: StreamTransformationFilter (Decryptor, New CryptoPP: : StringSink (// StreamTransformationFilter) // Base32Encoder); // string source UI-> Text-> clear (); GetData = QString :: fromUtf8 (output.c_str ()); UI- & gt; Text & gt; SetText (GetData);

Do I have any bugs that I remember?

I think you are losing data while converting from QString to QByteArray. Try it out: 

  QByteArray data = getData.toUtf8 (); ... getData = QString :: fromUtf8 (output.c_str ());

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....

wpf - Custom Message Box Advice -

Well, I'm using a custom window box that comes with some custom control boxes that accompany the text The producers who are displayed are called. I have a defined event, which has been subscribed through the original class, it gets burnt when clicking on the button. However, I can not see how to use it effectively, I would like to return one yes, whether yes or not, but obviously my code will continue to execute, so this Below is some example code to clarify the problem that the method has subscibed by clicking on the button. Message box window Public partial class custom message box: window {public representative message messagebox object sender, event events e); Public event messagebox handler messagebox document; Public Customs Box () {Initial group (); } Public Customsbox (String Message) {InitializeComponent (); This.txtdescription.Text = Message; } Public Customsbox (String Message, String Title, String First BTNtext) {Initialization (); This.lbltitle.Content =...
