Everybody knows that we should not enter our bank data, credit cards numbers being connected to the public wifi network.
Let's imagine that somebody goes to his bank's web site being in public network. Yes, his traffic can be captured but using https it's encrypted by banks public certificate. So none exept bank can decrypt this personal data.
All of this is in case when user is really sure that it's a public hotspot of the airport, not some hacker's one.
I'm wondering it it really so or it's not so easy?
