Q-Day: RSA and ECC Fall
The day a quantum computer can practically break today’s encryption (RSA, elliptic curves).
Open in the interactive tree →A cryptographically relevant quantum computer would compute keys with Shor’s algorithm in hours to days. When this happens is open; estimates of the qubits required keep falling. Those who have already migrated are protected; unprotected data and systems are not.
What it brings
- Decrypting today’s intercepted, insufficiently protected data
- A forced end to legacy cryptography in all systems
- A touchstone for the post-quantum migration
