(Post-Quantum) Cryptographic Right Answers

The post-quantum cryptography transition deadline has been accelerated to 2029, requiring developers to update their security practices immediately. While symmetric cryptography remains secure, all asymmetric cryptographic recommendations have changed significantly since 2024, with new standards like ML-KEM-768 for key exchange and ML-DSA-44 for signatures replacing previous approaches. The article provides updated cryptographic best practices for developers, emphasizing cloud-based key management services where available and highlighting the importance of code review using AI tools.
