# Post Quantum Cryptography (PQC) overview and why you should care!

**[John Savill's Technical Training](https://daily.dev/sources/john-savill)** · 10 min read · 0 upvotes · 0 comments

## Summary

Post-quantum cryptography (PQC) is becoming increasingly important as quantum computing advances threaten to break today's asymmetric encryption (RSA, public/private key systems) using algorithms like Shor's algorithm. Symmetric encryption (AES) remains quantum-resistant, but asymmetric systems need replacing. NIST has already standardized PQC algorithms, and Microsoft is rolling out quantum-safe algorithms across its services in phases through 2027. Organizations should inventory their use of asymmetric cryptography, make systems crypto-agile, adopt PQC libraries, and use private networking now to guard against 'harvest now, decrypt later' attacks where adversaries store encrypted traffic today to decrypt it once quantum computers mature.
