Over the course of the semester we’ll be using Gnu privacy guard and Knoppix 5.1 linux. I have an iso image of Knoppix and will burn cd’s for people in lab, provided you bring a blank cd. If you are comfortable burning your own copy or already have a Linux computer then you are all set. You may use your own machine for labs.
Gpg is available on line for all major operating systems. You should download a version that is compatible with the machine you use for email. E.G. If you read email on a windows pc, get a windows version of gpg. I tend to sign official emails using gpg. You should be suspicious of unsigned emails from my email address.
