This lab is designed to encourage you to investigate a number of the topics we discussed in class.
Security Certificates
Go to each of the secure web sites below and examine its security certificate. (In firefox, double-click on the padlock icon at the bottom of the window.) What differences do you notice?
Read about getting your own certificate for use with email. (You shouldn't try to do this now, as it takes some time.)
Wikis
By far the best known public wiki is the Wikipedia. Anyone can edit the articles there -- even you! Try it now: read the tutorial on editing pages and then go to the sandbox to practice. (A sandbox is a safe place to experiment where you will not hurt anything if you make a mistake.)
If you have expert knowledge on a particular subject, you may even wish to edit one of the regular articles, but this is not part of the lab assignment. (By the way, did you know that according to a 2011 survey, 90% of Wikipedia editors are male?)
