Misconception M1 / F3

Encryption does not mean you reached the right owner

Encryption means we reached the right owner.

Wrong claim

Why it feels true

A padlock on TrackPort looks like proof the phone is talking to Riverstone.

Precise correction

Transport Layer Security (TLS) 1.3, defined in RFC 8446 (August 2018), protects the bytes of a session and lets the client check a certificate for the name it asked to reach.

That check does not decide that the name was the company the customer meant, and it does not decide which person or which shipment is allowed.

If DNS sent the phone to a lookalike and the certificate matches that lookalike, encryption worked for the wrong owner.

MINI-CHECK

A customer on cafe Wi-Fi sees a padlock for track-riverstone-login.example and types a TrackPort password. What did the encryption prove?
