How can I implement logging and encryption in C++ and Java?

How can I implement logging and encryption in C++ and Java?

You can use libraries like Log4j for Java and spdlog for C++. For encryption, consider using OpenSSL for C++ and Java's built-in libraries.

Can you provide a code example for logging in C++?

Sure! Here's a simple example using spdlog:

#include <spdlog/spdlog.h>

int main() {
    spdlog::info("Hello, {}", "world");
    return 0;
}

What about encryption in Java?

In Java, you can use the javax.crypto package. Here's a basic example:

import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;

public class EncryptionExample {
    public static void main(String[] args) throws Exception {
        KeyGenerator keyGen = KeyGenerator.getInstance("AES");
        SecretKey secretKey = keyGen.generateKey();
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);
        // Encrypt your data here
    }
}

What libraries do you recommend for encryption in C++?

I recommend using OpenSSL or Crypto++. Both are widely used and provide robust encryption functionalities.
