If you are using a public wifi hotspot it's an untrusted network. Even encryption does not solve this. How do you prevent someone from just setting up an accesspoint and then sniffing on all routed data? In addition, for the operator of the wifi hotspot there is no incentive to setup a complicated encryption scheme: If you care about the security issues it's likely that you know how to solve them yourself (see below). If you don't care it's likely that you won't be able to setup a WPA password that is indicated in the SSID. The only solutions for this are: - Either you establish end-to-end security with each individual server you want to contact. Unfortunately this doesn't really work with HTTP today. - You open a secure channel to a trusted entity (such as a VPN provider you trust) and then route all data over this channel. Such solutions are available for less than $10 a month. If you think that option #2 is too hard for someone without any knowledge about security you've just identified a new business idea.
