For this assignment, you must implement the Data Encryption Standard $($DES$)$ algorithm with any programming language that you are comfortable with. The recommendation is to use $C++$ or Java. You can accomplish this assignment individually or by forming a team of $2$ students.

You can utilize the publically available tables$/$functions in order to implement the DES. You can find these permutation tables$/$functions in some reference books or over the Internet.

You algorithm should get a plaintext as well as a "secret key" from the user and then perform encryption $($generating the ciphertext from the plaintext$)$ and decryption $($generating the original plaintext from the ciphertext$).$

You can also select any "mode of operations" that you want. All the necessary technical materials are available in the posted lectures on Canvas.

You must submit all related files in a zip file on Canvas $($just one file for each group, submitted by the group leader$).$ Make sure to include a "ReadMe.txt$"$ file so that I know what you have done and how your program can be executed.
