🔐 Post-Quantum Cryptography: Key-Size vs. Security Lab (2D)

2D bit-security calculator: real GNFS, ECDLP and core-SVP hardness formulas compute classical and quantum security for RSA, ECC and ML-KEM — pick a scheme and a logical-qubit budget and watch Shor's algorithm break the classical vault only once it truly has enough qubits, while the lattice vault stays sealed.

This 2D companion trades the 3D version's decorative "cracking sphere" animation for the actual numbers behind the post-quantum migration story: a general number field sieve formula for RSA, a square-root Pollard's-rho estimate for ECC, and the core-SVP hardness model used in the real Kyber/ML-KEM design papers all compute live classical and quantum bit-security as you switch schemes and key sizes. The classical vault on screen only cracks when the logical-qubit slider actually reaches Shor's algorithm's real qubit requirement for that key size — not on a fixed timer — while the lattice vault has no such threshold at all on this chart, which is exactly why NIST standardized it.
