- With linked allocation, each file is a linked list of disk blocks; the disk blocks may be scattered anywhereon the disk. The directory contains a pointer to the first and last blocks of the file. Each block contains a pointerto the next block. Refer to the illustration below.

In this assignment, you will parse a string of words from a file into tokens using the strtok_s command with pointers and then use the Vigenere Cypher algorithm to encrypt and decrypt the parsed words. Before you can perform any encryption/decryption activities, the first step is to read in messages from a file and parse the messages into individual words. The Program: Setting up classes and understanding tokenization The first step in encrypting/decrypting messages is to parse the messages into words before applying the encryption/decryption algorithms to them. This parsing process is called “tokenization.” Read the contents of a file into this array using the getline command. The objective of this assignment is to demonstrate the use of pointers in a program utilizing c-strings and tokenization. The use of pointers is foundational in C++. This…1:34 b a 2. Different operating systems use different file allocation techniques to store files in the secondary storage device such as HDD. One of the techniques is "Linked allocation". In this technique, each file is divided into several data blocks of same size. Each data block has a link to its next block like a singly linked list. So, the data blocks are scattered on the disk. The directory contains a pointer to the starting and the ending data block of a file. The diagram below depicts a sample linked allocation system of a file Abc.txt: Directory entry File Start End Abc.txt 100 900 Data 900 Data Data block 1 block 2 Data block 3 block N Write a Java program to implement the linked allocation of a given text file Assgn1_2.txt (uploaded with the assignment) who's each block will contain maximum 50 characters.

- Experimenting with AES-”S symmetric key cipher. Note: You may use any programming language that provided libraries for AES. Descrion: This assignment consists of two parts:PART 1: write a program that uses AES-12/1 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and file outcome of the decryption, respectively. o To test this program, here's an example of an encrypted message a. its 128-bit secret key PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have Sirrst 96-bits of the 12S-bit secret key (last 9 bytes of the secret key are he 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, respetively.
