- PART 1 1. Using python, create a program with a function of enc_text(text, key) to encrypt the variable text using the provided key (executing a modified version of Ceasar Cipher). Follow these rules: а. The key will contain a word made up of the letters 'a' and 'b'. The cipher will use the key to know the direction of the shift: • 'a' - the character must be shifted upwards • 'b' - the character is to be shifted downward. b. The number of characters in the key will determine the number of positions to shift. c. The given text variable will only have characters from the ASCII table (values between 32 and 126). d. If the key is invalid (contains characters other than a and b or an empty string) or the text is invalid (empty string), no encryption will happen and the function returns the original text. e. The key will loop through again to accommodate the additional text characters if the text has more characters than the key. Brute force solutions will not be accepted and an iterative…PYTHON!!!!! Use the strategy of the decimal to binary conversion implemented in Project 4, and the bit shift left operation defined in Project 5 to code a new encryption algorithm. The algorithm should Add 1 to each character’s numeric ASCII value. Convert it to a bit string. Shift the bits of this string one place to the left. A single-space character in the encrypted string separates the resulting bit strings. An example of the program input and output is shown below: Enter a message: Hello world! 0010011 1001101 1011011 1011011 1100001 000011 1110001 1100001 1100111 1011011 1001011 000101 Program produces correct output given input: Test case: Test for Hello world!

The program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respectively. The program should print out on standard output the missing 4 bytes of the key in hexadecimal, the decrypted message and the time it took to find the correct key.o To test this part, here is the encrypted file (ciphertext2.dat), and the first 96-bits of the key (partial-key.dat) Hint: the original message starts with the word "Salam".

- Write a bash shell script program that prompts the user to enter a list of 10 student names and check the number of occurrences of "Emily". Your program should display the result. Sample input: Emily Susan Lily Ashley John Alex Nancy Tim Michael Emily Your program output should be: Emily appeared 2 timesTwo entities are using a secret code to communicate with each other. You have managed to intercept a message that reads as follows: :mmZ\dxZmx]Zpgy The message is obviously encrypted using a secret code. You have just learned that the used encryption method is based upon the ASCII code (available online). Individual characters in a string are encoded using this system. For example, the letter "A" is encoded using the number 65 and "B" is encoded using the number 66. The secret code takes each letter of the message and encrypts it as follows: if (OriginalChar + Key > 126) then EncryptedChar = 32 + ((OriginalChar + Key) – 127) else EncryptedChar = (OriginalChar + Key) For example, if the Key = 10 is used then the message "Hey" would be encrypted as: Character ASCII code H 72 e 101 y 121 Encrypted H = (72 + 10) = 82 = R in ASCII Encrypted e = (101 + 10) = 111 = o in ASCII Encrypted y = 32 + ((121 + 10) – 127) = 36 = $ in ASCII Consequently, "Hey" would be transmitted as "Ro$."
