How can I use OpenSSL in my C++ project?

To use OpenSSL in your C++ project, you need to install the OpenSSL library and include the necessary headers.

What are the basic functions I need to know?

You should familiarize yourself with functions like SSL_library_init(), SSL_CTX_new(), and SSL_connect().

Can you provide a simple code example?

Sure! Here's a basic example:

#include <openssl/ssl.h>
#include <openssl/err.h>

int main() {
    SSL_library_init();
    SSL_CTX *ctx = SSL_CTX_new(TLS_method());
    // Additional code...
}

How do I handle errors in OpenSSL?

You can use ERR_get_error() to retrieve error codes and ERR_error_string() to get a human-readable string.
