Harvest Now, Decrypt Later: The Attack You Defend Against by Doing Nothing

Somewhere, an attacker is recording your encrypted traffic. Not breaking it. Recording it. The bet is patient and simple: store ciphertext today, wait for quantum computers to mature, decrypt at leisure. The industry calls it harvest now, decrypt later HNDL, and it is the rare security threat wit...
