Your team was invited to present to a high school IT class to explain how cryptography works. In order to explain the basics, you decide to show the class a tool called, CrypTool. This web-based tool allows people to visualize encryption and decryption using common cryptography techniques. In order for the students to follow along with your demonstration, you need to create a tutorial for them. Together as a team, access CrypTool ( http://www.cryptool-online.org/ ). Click on the CrypTool link, then click Ciphers . Click and choose a type of cipher you would like to use under Classical Ciphers . Use CrypTool to do the following: Determine at least five pieces of data to encrypt and decrypt Determine a key (or a set of keys) that is different from the samples provided in CrypTool. Attempt to break the encrypted ciphertext data using the cryptanalysis tools provided by CrypTool. Note: It may not always be possible to break the ciphertext. Regardless of the attempt's outcome. Document the steps taken and relevant observation notes. Create a tutorial with text and images (screenshots) on how to use CrypTool. Include the following: Steps needed to encypt data Steps needed to decrypt data Steps taken to attempt to break the encrypted data using the cryptanalysis tools provided by CryptTool Submit the tutorial to the Assignment Files tab above. .
