In C language: You are a foreign spy, and you are trying to communicate with your buddy across the globe. You wish to ensure that your message is entirely confidential, upholds its integrity, and is accessible by your buddy. Your message is written in a text file, you are going to create an encryption scheme with a shared default password ("potatoes") between you and your buddy, and your will is to transmit your ciphertext to your buddy in hopes that he can decrypt it. Part 1: Write a program that would read your plaintext message from the text file. Create a caesar cipher that can be accessible by a unique password ("potatoes"), and write your ciphertext to a new text file. The encryption algorithm should shift your characters by adding 5 to your plaintext ASCII values, and the decryption algorithm should shift your characters by subtracting 5 from your ciphertext ASCII values Part 2: Read your ciphertext message from the newly created text file, convert it back into plaintext, and write the plaintext message into a new text file. NOTE: Your new plaintext message should be the exact same as the provided one. Due date: 04/1/2024 Read from file Apply caesar cypher Only letters should be shifted over, not spaces or punctuation. Upper case letters should remain uppercase Lower case letters should remain lower case letters If you have questions about the caesar cipher please contact Sam or Sarah or Dr. Chamon Prompt user for password o If password is correct carry on, if not, end program ⚫Create new encrypted.txt file ⚫Write encrypted text to encrypted.txt file ⚫Read encrypted text from encrypted.txt file ⚫Decrypt encrypted text Write decrypted text to a decrypted.txt file plaintext.txt: She sells seashells by the seashore.
