Please verify or correct the following.

1. If I use a wi fi that does not use encryption, all information / data that travels between my computer & the wi fi access point can be accessed by anyone with sufficient sophistication / knowledge / tools.

2. Even if I connect to a https site, the information between by computer & the access point is available to anyone with sufficient sophistication / knowledge / tools.

My conclusion is that the use of an unencrypted wi fi network is not completely secure.

Thanks for your time.

Sincerely,

1. It doesn't require much sophistication to snoop traffic on an unencrypted wireless network.

2. Yes, someone can sniff the traffic you are generating with a web site. But since it's over an SSL tunnel, they would have to have be able to crack the encryption which is very difficult. This scenario would be no different than someone pulling your traffic over the internet. The issue in addition to the obvious data security of sending data over the air unencrypted to the access point is that it allows others to be on the same wireless network as you. The ramifications of this is the exposing of your computer to malicious attacks and other types of hacker attacks such as man in the middle.

Your conclusion is not entirely correct. The use of an unencrypted WiFi network is never secure.

No one is going to crack any https connection, so you're safe there. But all else you said is correct. There is also the possibility of their being able to get usernames and passwords if you need to sign in over an unencrypted connection before starting the https connection.

The biggest worry with an unencrypted network isn't people monitoring your web surfing - it is the possibility that they can enter your machine or any other machine on the network and extract data. Of course, if they use your connection, you lose that bandwidth, too, even if you use https.
