Post-quantum cryptography is gaining attention despite the uncertainty surrounding the existence of quantum computers. The new standards promise safer, more resilient, and flexible encryption methods. The debate around quantum computers is ongoing, with conflicting opinions on when they will pose a threat to current cryptographic systems. Post-quantum cryptography offers a diverse set of solutions based on various mathematical problems, providing a backup plan if one method is compromised. The modern designs focus on addressing implementation pitfalls, offering flexibility in use cases, and avoiding reliance on a single cryptographic problem. Despite the skepticism, post-quantum cryptography aims to revolutionize encryption practices and reduce vulnerabilities in the digital realm.
