The post-quantum era is upon us, and new cryptographic algorithms are now available. Python developers that use encryption, signatures, or other cryptographic operations in their code must update their Python code. There are already Python implementations, but they can be problematic to use as a drop-in.In this session, We will learn about post-quantum cryptography algorithms and why we should use them.We will also learn to combine the old and new algorithms securely, ensuring we maintain our classical assurance and certification while preparing for the quantum challenges.
