Q‑Day Explained: How Quantum Computing Threatens Today’s Cryptography

Q-Day, the day a quantum computer will be powerful enough to break current encryption standards, is an inevitable threat. This summary explains how quantum algorithms like Shor’s and Grover’s will compromise both asymmetric and symmetric cryptography, the severe consequences for data confidentiality and digital trust, and why the "Harvest Now, Decrypt Later" attack vector makes immediate migration to post-quantum cryptography a critical priority for all organizations.
