Below we explain the purpose of post quantum cryptography, how post-quantum encryption works and why we need quantum-resistant cryptography already today - and not once the era of quantum computers has started. But quantum computers can also be turned into unprecedented surveillance machines and threaten our cybersecurity: The race is on between quantum computers and post-quantum cryptography! The final result of this NIST post quantum cryptography standard is being awaited eagerly by the crypto community. Therefore, post quantum cryptography algorithms and conventional algorithms have to be combined in a hybrid approach. As quantum computers are about to become a reality, we must be one step ahead with post quantum cryptography to keep all data secure - now and in the future!
