How can I use OpenSSL with C++11?

What are the basic steps to use OpenSSL in a C++11 project?

To use OpenSSL in a C++11 project, you need to install OpenSSL, include the headers, and link the libraries.

Can you show me a simple example of encrypting data with OpenSSL in C++?

Sure! Here's a basic example:

#include <openssl/aes.h>
#include <openssl/rand.h>

void encrypt(const unsigned char *key, const unsigned char *data, unsigned char *encrypted) {
    AES_KEY encryptKey;
    AES_set_encrypt_key(key, 128, &encryptKey);
    AES_encrypt(data, encrypted, &encryptKey);
}

What libraries do I need to link when compiling my C++ code with OpenSSL?

You typically need to link against libssl and libcrypto. Use -lssl -lcrypto in your compile command.

Are there any common pitfalls I should be aware of when using OpenSSL?

Yes, make sure to handle memory management properly and be aware of the security implications of key management.
