Android NDK Decrypter in C++ (Fix Memory Leak) -- 2

I work in an IPTV, we make UDP encrypted transmissions of streams, the cryptor is made in C++ and the decryptor too and this is used with the Android NDK to be able to play the transmission from Android, the problem is that while we are decrypting the stream, the ram memory consumption is increasing significantly, in the Android Profiler you can see how the native code (c++) is increasing its ram consumption by almost 1mb per second, which makes the app crash when ram memory runs out, even sometimes it crashes the box, I need a C++ developer who has experience with Android NDK and AES encryption to help me solve this memory leak. In the photo below you can see that the object that is not being released correctly corresponds to a: operator new(unsigned int) But nowhere in the code do I have this statement. We have hired a person to create this cryptor, but this person was not able to find the bug and now we have the faulty cryptor. PDT: Our cryptor and decryptor also have random keys for decryption

I have successfully tackled even the most challenging projects. Over the past 10 years, I have delivered over a thousand successful projects to organizations in the enterprise and medium tiers. Based on your project description, it seems that you are facing a memory leak issue in your UDP encrypted transmission process for Android using the Android NDK. I understand that the ram memory consumption is significantly increasing during the decryption process, which leads to app crashes and even crashes the box at times. As an experienced C++ developer with expertise in Android NDK and AES encryption, I would be glad to assist you in resolving this memory leak issue. However, to better understand the problem and devise an appropriate solution, I would require some additional details about your implementation. Could you please provide me with the following information? 1. Can you share any specific code snippets related to the decryption process and memory management? 2. Are you using any third-party libraries for encryption or decryption? If so, please provide details about those libraries. 3. Have you performed any memory leak analysis using tools like Valgrind or similar profilers? If yes, please share the findings. 4. Is the memory leak observed consistently, or does it occur under specific circumstances or scenarios? 5. Can you explain more about the random key generation process for decryption? Once I have a better un...

Hi, I have great experience in implementing symmetric cryptographic algorithms like AES, ChaCha20 as well as assymetric ciphers like RSA and ECC from scratch in C or C++ or by using libraries like libcrypto from OpenSSL. I see that you are facing a memory leak issue in your code, and needs fixing. Since I have lots of experience in both C and C++ programming and with cryptographic ciphers and I believe I can help you with this. Please send me the code dealing with cryptography for me to fix. Please feel free to contact me via chat so that we can discuss further and start working on this amazing project right away!!! Best Regards, Aravind A
