At its core, password cracking is an exercise in reversing the intended one-way relationship between secret and verifier. Systems rely on secrets—passwords, keys, tokens—to authenticate users.

Yet attackers exploit predictable human behaviors (reused passwords, common phrases), weak implementations (unsalted hashes, poor entropy), and side channels (password reset flows, social engineering) to reduce the search space and bypass defenses.
