Migrating Public-Key Infrastructure Before Cryptographically Relevant Quantum Computers (CRQC)

Shor's algorithm rendered classical asymmetric cryptography (RSA, ECDH, ECDSA) obsolete against future quantum adversaries. 'Harvest Now, Decrypt Later' (HNDL) attacks threaten encrypted data transmitted today. PQCEcosystem coordinates the algorithmic and operational transition to quantum-safe mathematical lattices.
