Post-quantum cryptography (PQC) refers to cryptographic algorithms and protocols designed to withstand attacks by quantum computers. PQC focuses on developing encryption and key exchanges algorithms that rely on mathematical problems believed to be resistant to quantum attacks. PQC aims to ensure today’s protected data remains secure in the future, even if powerful quantum computers become widely available. So, the challenge for all software ecosystems is that they must evolve to support PQC. For example in France, ANSSI requires to switch into hybrid mode in 2025 and full PQC support in 2030.
