Let the user choose encryption or decryption.
For encryption, let user input the key in Hexadecimal number, the plain text in Hexadecimal number, output the ciphertext (in hexadecimal numbers).
For decryption, let user input the key in Hexadecimal number, the ciphertext (in hexadecimal numbers), output the decrypted message (Hexadecimal number).
Both encryption and decryption should output the different operation results for each round like the following:
For example:
Round 1:
E(R0) = ...... (Hex or Binary)
K1 = ……
E(Ro) xor K1 =
S-box outputs = ……
f(Ro1, K1) = …..
L2 =R1 =…….
La = Ra
Round 2:
.....•
No Encryption/Decryption libraries or functions provided by the third party are allowed.
Submit your program codes to Moodle with the notes of how to compile and run your program.
When the given integer variable numberOfPackages is:
greater than 12, output "Needs more than one box".
between 5 inclusive and 12 inclusive, output "Large box".
between 0 exclusive and 4 inclusive, output "Small box".
less than or equal to 0, output "Invalid input".
End with a newline.

- 1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with three different lights, each of which can be turned on or off, projecting onto a glass screen: We can create eight different colors based on the absence (0) or presence (1) of light sources R,G and B: R G B Color 0 0 0 Black 0 0 1 Blue 0 1 0 Green 0 1 1 Cyan 1 0 0 Red 1 0 1 Magenta 1 1 1 0 Yellow 1 White 1 Each of these colors can be represented as a bit vector of length 3, and we can apply Boolean operations to them. a. The complement of a color is formed by turning off the lights that are on and turning on the lights that are off. What would be the complement of each of the eight colors listed above? b. Describe the effect of applying Boolean operations on the following colors: Λ 1. Red(100) ^ Magenta(101)= Blue(001) 2. Bue(001) | Green(010)= 3.
