UNDERSTAND THE IDEA
Guessing and key strength
This toy exercise is not a real password attack. Real account security depends on rate limiting, password hashing, MFA and server design. Cryptographic keys have different strength properties from human passwords.
Try a three-digit training PIN. Run a tiny dictionary list, then a bounded exhaustive search of 000–999.
