This project uses an Enigma® machine simulator. It functions like the Enigma machines used during WWII. This example has been included to help you better understand how encryption worked in the early days. It’s a great learning tool for when you first start exploring the subject of cryptography. Enigma machines provided fairly good encryption strength for their day. Modern cryptographic systems are much more secure than Enigma machines.
Pay attention to the colored paths as you type. The red path goes through the three rotors, bounces off the reflector, becomes green, and then goes back through the three rotors. The right rotor moves with each keystroke. If it completes one full cycle, it will advance the middle rotor and, subsequently, the left rotor as well.

answer the following questions:
- Why did Enigma machines use multiple rotors?
- How did WWII cryptographers know which rotor settings to use?
Your well-written paper should meet the following requirements:
- Be two to four pages in length
- Contain an illustrative table or a diagram created from properly cited external references
- Include two credible external references in addition to the textbook
- Formatted according to APA writing guidelines.
