Quantum Is a Time Bomb for Today’s Encryption

Описание: Every encrypted message you send today could be decrypted years from now.

In this video, you’ll learn why quantum computers threaten today’s encryption, how attackers can “harvest now and decrypt later,” and what post-quantum cryptography (PQC) does differently to keep data safe for decades.

We break down lattice-based cryptography, explain why algorithms like CRYSTALS-Kyber and Dilithium were standardized by NIST, and show how modern systems are upgrading before quantum computers arrive. You’ll see how hybrid deployments work, what the real performance tradeoffs are, and how organizations can migrate without breaking the internet.

If your data needs to stay private long after it’s created — medical records, legal files, designs, or financial data — this transition matters now, not later.

This video is part of the Enginerds Fundamentals series — clear, calm explanations of the technologies shaping modern software and systems.
