Post‑Quantum Cryptography
Encryption
Crypto designed to stay safe even if powerful quantum computers exist.
Definition
Post‑quantum cryptography is encryption designed to resist attacks from future quantum computers.
In plain English
Crypto designed to stay safe even if powerful quantum computers exist.
Why this matters
Why it matters: Some current encryption methods could become weaker if large quantum computers arrive.
Example
Example: A service starts using quantum‑resistant algorithms for key exchange.
