How can I handle OpenSSL errors in C++11?

What are some common OpenSSL error handling techniques in C++11?

In C++11, you can handle OpenSSL errors using functions like ERR_get_error() and ERR_error_string(). These functions help retrieve error codes and their corresponding messages.

Can you give me an example of how to implement error handling in my code?

Sure! Here's a simple example:

#include <openssl/err.h>

void handleErrors() {
    unsigned long errCode = ERR_get_error();
    if (errCode) {
        char *errorString = ERR_error_string(errCode, NULL);
        std::cerr << "OpenSSL Error: " << errorString << std::endl;
    }
}

What should I do if I encounter a specific error code?

You can use the ERR_reason_error_string() function to get a more detailed description of the specific error code. This can help you understand the issue better.

Are there any best practices for error handling in OpenSSL?

Yes, always check return values of OpenSSL functions, use a centralized error handling function, and log errors for debugging.
