Cryptography Basics | Can't complete lesson 1.2 Guided Exercise

I have completed the ‘Instructions’ and the ‘Tasks’ sections, but for some reason on the ‘Machines’ section (when I try to copy to the clipboard it is not copying.

The lab itself is found on the Instructions Tab. This is where you will find the steps you need to perform any given lab.

The Tasks tab hosts questions related to the lab work.

The Machines tab is not a required part of any lab. There is no task to perform here. It’s main purpose is to allow you to move between virtual machines when a lab has more than one. It also is the place to reset your lab if you want to start all over. Lastly, it’s a place you can copy and paste into the lab environment from your desktop.

There is no requirement to paste anything into the lab.

If you have completed all the lab steps on the Instruction tab, and answered all questions on the Tasks tab, then you are done.
