Crypto++ and QByteArray

[Urvin]

Please, help me to crypt a Qt byte array using Crypto++ library and TEA algorythm!

Looking at QCrypto from qt-apps I see, that to crypt standart string with a byte key I should use this:

string lInputText;
    string lResultText;
    QByteArray fEncryptionKey;
 
    ... 
 
    byte lKey[TEA::DEFAULT_KEYLENGTH];
    byte lIVector[TEA::BLOCKSIZE];
 
    StringSource(reinterpret_cast<const char*>(fEncryptionKey.data()), true,
                 new HashFilter(*(new SHA256), new ArraySink(lKey, TEA::DEFAULT_KEYLENGTH))
                );
    memset(lIVector, 0x00, TEA::BLOCKSIZE);
 
    CBC_Mode<TEA>::Encryption Encryptor(lKey, sizeof(lKey), lIVector);
 
    StringSource(lInputText, true,
                 new StreamTransformationFilter(Encryptor,
                    new HexEncoder(new StringSink(lResultText)))
                 );

string lInputText;
    string lResultText;
    QByteArray fEncryptionKey;
 
    ... 
 
    byte lKey[TEA::DEFAULT_KEYLENGTH];
    byte lIVector[TEA::BLOCKSIZE];
 
    StringSource(reinterpret_cast<const char*>(fEncryptionKey.data()), true,
                 new HashFilter(*(new SHA256), new ArraySink(lKey, TEA::DEFAULT_KEYLENGTH))
                );
    memset(lIVector, 0x00, TEA::BLOCKSIZE);
 
    CBC_Mode<TEA>::Encryption Encryptor(lKey, sizeof(lKey), lIVector);
 
    StringSource(lInputText, true,
                 new StreamTransformationFilter(Encryptor,
                    new HexEncoder(new StringSink(lResultText)))
                 );

To copy to clipboard, switch view to plain text mode 

But what should I do if I have QByteArray InputData, QByteArray Key and I want to have QByteArray OutputData at output?
Thanks!
