A Web page is secure, if you see the little lock icon turned on in your browser. All traffic to and from a secure Web site is strongly encrypted, so no man-in-the-middle can eavesdrop on any of the information, including the passwords. The only time I've been able to capture information is when somebody was sending it without encryption. By the way, 3G cell connections are encrypted by default, although the encryption method isn't among the strongest, and can be broken by people with the right software, fancy hardware and a lot of patience. At home, you should make sure your Wi-Fi router is encrypted. All routers have the option to turn it on, but they come with it turned off. There are two types of Wi-Fi encryption. The older, weaker, method is WEP. The newer and stronger is called WPA. If your router gives you a choice, choose WPA along with a good long password. I secure everything I can. I don’t believe the often heard and historically naive statement "If you've nothing to hide, then you've nothing to worry about." _______________________________________________ MacGroup mailing list [email protected] http://www.math.louisville.edu/mailman/listinfo/macgroup
