Why does not having a WiFi password mean that the information must travel unencrypted?
And why is a password enough to encrypt that information, even if said password is written in large letters on a wall for everybody to see?
I'm sure that there are a good technical reasons, but at the same time it seems like there should be a better way to have convenient and safe WiFi networks in public spaces.
- beatgammit 7y agoI think the answer is that public WiFi hotspots don't have any way of verifying that they are who they say they are, whereas TLS works because you have a trusted third party (the CA) that verifies the keypair. So, if a WiFi hotspot used something like TLS, the data would be encrypted, but you have to way to verify that you're not going through a malicious third party's hotspot on the way to the public WiFi.
