Objective: Explain cryptography algorithms and their basic characteristics.

See attached PowerPoint presentation: Lab – Passwords
Assignment:
Complete the lab in the Lab – Passwords.pptx presentation.
This is an advanced lab that involves password hashing, so it is being presented as an extra credit opportunity.
To submit proof of completion for this lab, post the plaintext the three passwords you created at the end of the lab (SHA-512, MD5 and SHA-256) into the provided form in today’s Google Classroom post.

Objective: Compare and contrast basic cryptography concepts.

See PowerPoint presentation: 6.1.4 – Steganography
Assignment:
Begin reading the 6.1.4 – Steganography.pptx presentation.
Complete the lab in the Lab – Steganography.pptx presentation.
Turn in the resulting “image4.jpg” file with a message of your choice hidden in the image using the steghide app. Upload this image to today’s Google Classroom assignment post. We will use these images in tomorrow’s class session. (So keep your messages classy!)
During tomorrow’s Late Start class session, we will read the Case Study – Steganography document and be prepared to answer the questions at the end.
A Google Form will be provided to answer the Case Study questions tomorrow morning.
Follow along with the in-class demonstration to learn how the Caesar Cipher (also known as the Shift Cipher) works, and how you can use it to encode and decode text messages.
Follow the Instructable to learn how keywords can be incorporated with this cipher to make it more difficult to decrypt.
I have placed 8 encrypted messages around the perimeter of the room. Work together to decrypt them all! Submit a Google Doc to my Google Classroom page with the decrypted messages by the end of the day tomorrow.
Some of the decrypted messages lead to treasure! The first to decode each message gets the goods!
Remember, you may work together, but each student must submit their own original document to the Google Classroom page by tomorrow to receive credit for the lab. Don’t put more than one name on your document, and don’t submit someone else’s document as your own!

This week we will be working in the classroom with a specialized Operating System installation. We will be using a Virtual Machine software called VirtualBox to installing a specialized OS (Kali Linux) in a virtual environment that we will use in the second half of our course.
I will distribute the required files in class today. If you did not receive the files or if you were not in attendance today, you will need to see me and I will show you where to download the files directly.
In your Downloads folder, you should have a subfolder called “VirtualBox 6.0”. Inside this folder, you should have four files: a VirtualBox .dmg file, a Kali Linux 2019 .ova file, an Oracle_VM .vbox-extpack file, and a UserManual.pdf file. If you are missing any of these files, please see me immediately to get them.
I will instruct you in-class on Thursday how to install VirtualBox VM in OSX, and how to load the VirtualBox extension pack and the preconfigured Kali Linux package.
We will walk through the configuration and testing of Kali on Friday, and I will explain some of the unique and powerful features of this specialized flavor of the Linux operating system.
Kali Linux will be required for the second half of the class, and you must complete your VirtualBox VM Kali Linux installation in class by Friday, October 25th to receive credit for this Lab Activity.
