With Shor's algorithm looming, the web is transitioning to Quantum-Safe standards. Learn how to implement PQC at the application layer.
The 'Q-Day' Preparation
Standard RSA and ECC are no longer sufficient for long-term data security. In March 2026, the global shift to Post-Quantum Cryptography (PQC) has reached the frontend. As a developer, you need to understand how to handle lattice-based signatures and key encapsulation in the browser.
Why This Matters for Frontend
•Client-Side Encryption: Protecting sensitive user data before it hits the wire.
•Browser APIs: Mastering the new PQC-enabled WebCrypto standards.
•Compliance: Financial and medical apps now require quantum-resilience by law.
