Attached is my attempt at making a small toy S3 client without any other dependency besides libcurl and OpenSSL. Was tested mainly on MinIO (RIP) locally, so I would expect some bugs when using it against AWS, although I was able to play with it on some open access buckets
Be aware that I am not a C++ programmer and this project was indeed done to learn a bit of C++ myself :')
Feedback on any of the code, either on gtest, or the benchmarking section or the core itself is welcome!
You may want to look into coroutines so that the data can be fetched asynchronously.
