Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to protect digital data against attacks by future quantum computers. As quantum computing advances, the threat to conventional encryption becomes increasingly real: data encrypted today can be harvested now and decrypted later, making key exchange the most urgent area to migrate. With NIST's standards now finalized (ML-KEM, ML-DSA and SLH-DSA), governments worldwide target migration between 2030 and 2035.
Modern infrastructure, languages (for example, Java since JDK 24) and frameworks are increasingly providing native PQC support in their latest versions. Enabling it, though, requires upgrading from older releases or adjusting configurations. Organizations should mandate quantum-resilient cryptography for greenfield projects while accelerating migration roadmaps for legacy systems.
