For this problem, solve by hand or write a program (perhaps in Python).If you write a program, please submit the code as a second submission file, as described above.Problem 2 !This problem involves cryptanalyzing a Vigenère cipher, which you may read about on Wikipedia:https://en.wikipedia.org/wiki/Vigen%C3%A8re_cipher. Vigenère ciphers can generally be de-ciphered using Kasiski examination, which is discussed on the Wikipedia page.You can find some ciphertext produced with the Vigenère cipher under a certain key on our coursewebsite at: https://cseweb.ucsd.edu/classes/fa21/cse107-a/resources/hw1/ciphertext.We have also provided sample decryption code at:https://cseweb.ucsd.edu/classes/fa21/cse107-a/resources/hw1/decrypt.py.Encrypting a plaintext letter with a key letter A results in no change, encrypting with a key letterB results in an increment by one place in the alphabet, encrypting with a key letter C results in anincrement by two places, and so on. Assume that the original plaintext contains only uppercaseletters (A-Z) and no spaces or punctuation.For example, encrypting the plaintext ATTACKATDAWN with the key BLAISE results in the followingciphertext:PlaintextАТТАСКАTDAWNKeyCiphertext BETIUOBEDIORBLAISEBLAISEThe goal for this part of the homework is to figure out what key was used to encrypt your ciphertext.(a)What is the key?(E,free to reference sections of your submitted code, but please write your explanation in clearEnglish sentences.How did you recover the key? Explain your methodology at a high level. Feel

with python do whis: Edit or delete a user profileWhen the user chooses 2, the first thing that it should do is to check whether the user information is loaded in the program (i.e., check if the user information is passed to the function that generates recipe recommendations). If the user information is passed to the function (i.e., the user chose option 1 before choosing option 2), the program should show the user the following menu:Hello (user name)You can perform one of the following operations:1) Delete your profile2) Edit your profilea. If the user chooses 1, perform the following subtasks to delete a user profile:1- Search for the user profile in the file userInformation.txt using the user name in read mode; once you find the user profile (i.e., the line that contains all the user information), pass it to a function that deletes the user information.2- The function should create a temporary file called temp.txt in write mode and search the file userInformation.txt in read mode…
Create a program in C language for reading and writing student records. Submit all necessary source codes and files to run this program (it is recommended to compress all files and submit a single file). First create text file "student_records.txt". The file should look like: Name Surname Quiz 1 Quiz 2 Quiz 3 Ada Lovelace 93 88 97 Babbage Turing Нopper Charles 26 80 70 Alan 74 85 92 Grace 99 87 100 a. Read the file contents and load them into an array of Record structs. b. The record struct has the member variables: o char array name o char array surname o int quiz_1 o int quiz_2 o int quiz_3 c. Write a function that calculates a students quiz average. The function takes a Record struct and returns a double. d. Create two new records for students inside your main program. e. Create a new text file with the new records to a a file called "student_records_new.txt"
Text Encryption Encryption plays an important role in protecting messages that are transmitted across the network. There are many symmetric and asymmetric encryption techniques that can be used in order to encrypt text messages. Some of these techniques are Caesar, Rows-Columns Transposition, Rail- fence, and Playfair cipher encryption as well as advance encryption algorithms. In this project, you are required to write a code that is capable of encrypting any given text (or text file) into a cipher text using any two different methods. You should prompt the user to choose the method that they would like to encrypt their text from a given list. Challenge: develop your code to decrypt the cipher text that is encrypted above Example: Assume the text TO SERVE AND TO PROTECT is required to be encrypted using Row-Column with the password ALERT Then the text message in Rows-Columns Transposition will become: TVTTSAPCOEOEENRTRDOX. The same text message in Rail-fence with depth of 4 would…

implementation of Caesar Cipher:You are required to implement the Caesar Cipher encryption/decryption algorithm in Python. Remember to implement the algorithm in such a way that it takes a file as input, encrypts it and store in the current directory. This encrypted file must checkable. The implementation must have a decryption procedure which takes the encrypted file from the current directory, decrypts it and store it with some specific name in the current directory. The name should be different from the original file so that it can be verified.
You are a cyber investigator, your task is to write a python program that can read file signatures from a file and save them into a list. Each file signature is an element of your list.

In this assignment, you will create a Java program to search recursively for files in a directory.• The program must take two command line parameters. First parameter is the folder to search for. Thesecond parameter is the filename to look for, which may only be a partial name.• If incorrect number of parameters are given, your program should print an error message and show thecorrect format.• Your program must search recursively in the given directory for the files whose name contains the givenfilename. Once a match is found, your program should print the full path of the file, followed by a newline.• You can implement everything in the main class. You need define a recursive method such as:public static search(File sourceFolder, String filename)For each subfolder in sourceFolder, you recursively call the method to search.• A sample run of the program may look like this://The following command line example searches any file with “Assignment” in its name%java FuAssign7.FuAssignment7…
