Obfuscation and reverse engineering deterrents for C++ Win/OSX app -


I've got a C + + app that ships on Windows and OSX. It communicates with our backend with TCP (OpenSSL, encrypted with niche). I would like to throw some speed parallels for those people who are trying to reverse the protocol engineer and / or separate the executable.

Skype does an outstanding job of this, that's why you will not get many Skype speakers. It's really good that what it does:

I need some suggestions on how to complete such stuff. Are there business products that make the code harder to analyze statically?

  • Prevent GDB from engaging in your program (it can be worked around, but some casual searchers will be away)

  • Your product stored outside the text segment of the executable At least some code, for example, or in the external (encrypted) shared library.

  • Minimize security by not storing any sensitive string data in plain text; Run "wire" against your executable, and if you can see anything that is used in the protocol If you are useful to someone trying to find out, then encrypt it.

  • GCC's Foam-Frame-Pointer option can make debugging more painful (but can interact with C + + exceptions poorly).

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
