How can I implement user authentication in C++?

You can implement user authentication in C++ by using libraries like OpenSSL for secure password handling and SQLite for user data storage.

What are the steps to securely store passwords?

First, hash the password using a strong algorithm like bcrypt. Then, store the hash in your database instead of the plain text password.

Can you show me a code example for hashing a password?

Sure! Here's a simple example using the bcrypt library:

#include <bcrypt/BCrypt.hpp>

std::string hashPassword(const std::string& password) {
    return BCrypt::generateHash(password);
}

How do I verify a password against the stored hash?

You can verify a password by using the BCrypt::validatePassword function, which compares the plain text password with the stored hash.
