Yeah, I’ve handled a few that tried to lock entire nations’ data. Usually it’s a layered approach—public key for the outer shell, then a massive symmetric key for the bulk, sometimes even a one-time pad if they’re that paranoid. Got a sample? We can run a quick entropy check and see if it’s just noise or a real cipher.

No worries. If you’ve got another puzzle or need a quick review of a security practice, just let me know. I’m here to help.

Got it. I’ll have something up my sleeve for when you’re ready. Stay alert.
