    this is for encrypting

    std::string EncryptManager::encode(QString text)
    {

    CryptoPP::byte key[MAX_ENCRYPT_KEY_SIZE], iv[MAX_ENCRYPT_IV_SIZE];

    key[i] = mKey[i];

    for(int i = 0; i < MAX_ENCRYPT_IV_SIZE; i++)
        iv[i] = DEFAULT_ENCRYPT_IV[i];
    
    std::string plaintext = text.toStdString();
    std::string ciphertext;

    stfEncryptor.MessageEnd();
    
    return encode64(ciphertext);
    

    }

    this is for decrypting

      @Bharth You did not post stack trace.
      Did you actually try to debug your app to see where EXACTLY it is crashing? This is first thing to do...

        In addition to provide the stack trace as asked before, are you using the same compiler to build the library and your Qt project?

              @Bharth Please just say whether you used SAME compiler to build both...

                Could it be possible you share the actual command/settings used for every build you did (Boost, libcrypto, Qt app)?

                      @Bharth mmm no debug settings for Boost... I'm suspicious that you might be mixing release and debug version of the application and libraries.
