What are quantum-resistant algorithms—and why do we need them?

What are quantum-resistant algorithms—and why do we need them?

Luckily, symmetric-key encryption methods are not in danger because they work very differently and can be secured by simply increasing the size of the keys they use—that is, unless mathematicians can come up with a way for quantum computers to break those as well. But even increasing the key size can’t protect existing public-key encryption […]
