How can I use cryptography in C++?

You can use libraries like OpenSSL or Crypto++ to implement cryptographic functions in C++. What specific functionality are you looking for?

I'm interested in encrypting and decrypting messages.

For that, you can use symmetric encryption algorithms like AES. Would you like a code example?

Yes, please provide a simple example of AES encryption.

Here's a basic example using Crypto++:

#include <cryptlib.h>
#include <aes.h>
#include <modes.h>
#include <filters.h>

using namespace CryptoPP;

void Encrypt(const std::string& plainText, std::string& cipherText, const byte key[AES::DEFAULT_KEYLENGTH]) {
    // AES encryption code here
}

Let me know if you need more details!
