I need to create a Transposition Cipher in Java that runs in Eclipse. The programs need to ask the user to encrypt or decrypt, read/accept a user's text file(.TXT) (NOT PLAIN TEXT), and save it as a new text file (.TXT). Please include as many comments as possible that help explains each line of code.

Write a python program that scans in a large number of tweets from a file, and prints the top 5 hashtags. Approach Parse each word in the file Find a way to isolate the hashtags from the rest of the tweet Compute the frequency of each unique hashtag.  Find the top 5 hashtags. Caveats 1. Because this is public dataset, there are many tweets that use special characters that may cause issues during reading in your file. To avoid this, explicitly specify the encoding mode in open when reading in the file. with open('twitter_data.txt', 'r', encoding='utf8') as f: 2. When parsing hashtags be sure to change everything to lowercase. There are cases in the file where two hashtags are the same but differ in case. 3. There is no standard way of sorting a dictionary based on the values. Python gives you access to a sorted function where you can pass in a collection and also specify a comparator which outlines how you want to sort the values. This can be done with a one line lambda function.

Please explain in C++ thank you

I need a help with my python activity. This requires 2 clients and 1 server. This is a system to support an online math contest.   Rule: There are two participants answering at the same time.   The host is responsible in starting up the server, after that they wait for the clients. When the two clients are connected, they must send the message: READY to the server. When the server receives the two READY from the clients, the contest starts.   The server will display 3 questions one after another which can be answered in 30 secs each. 11+10 = 21 10+22 = 32 10+10 = 20   The participant with most correct answers wins.   At the end of the program, the server must show the results. ex: Client1 WINS! 2/3 Client2: 1/3

2 Please help me, I am using Java and it has to be AES As part of this project, you need to consider the following steps in your implementation: 1. With an AES encryption algorithm 2. Sender: Given a document X, write a program that can encrypt X with a passsword. Let’s say the password-protected document is Y 3. Receiver: Given Y, write a program that can ask the user to enter a password and perform decryption process to extract the original document X 4. During your implementation, you can also consider how to incorporate the following case: how a given document can be securely shared with several users. For example, if X is a document, then your platform can support multiple (authorized) users to securely access X.

Write a Java application for a server that listens to a client. The server should run on port 8250. Once the server is running it should output “Server is starting….”, then it should wait to receive a message from the client. Once it receives the message, it should close the socket. Create a client that sends a message to the server through port 8250. The message that should be sent to the server should be the sum of two numbers. Once it sends the message, it should close the socket. Figure 2 shows messages from the server:

A parking house has place for 107 cars. There are many turnstiles letting cars in and out. As cars come in a shared counter is incremented. As cars leave the house, the shared counter is decremented. Implement the shared counter as a monitor in Java. See to it that if there are 107 cars in the house, processes trying to increment the counter get delayed until some car leaves the house (this will cause the turnstile to be kept closed without letting the car in, but you do not have to worry about this, you are not implementing the turnstile processes!)

Encrypt Caesar cipher is a kind of substitution cipher. Instead of using a substitution table, the alphabets are rotated by a number (a key). For example, if the key is 3, plaintext alphabet a would become d, and plaintext alphabet z would become c. Write a  program that implements the Caesar Cipher. You program will first prompt for the key and then for the mode (E for encryption and D for decryption) and finally for the message to be encrypted / decrypted. Your program will then output the encryption / decryption message. For this question, the input message may consists of any character, the program should encrypt or small letter case a to z only. All other characters should be kept intact after encryption or decryption.

Create a client that sends a message to the server through port 8250. The message that should be sent tothe server should be the sum of two numbers. Once it sends the message, it should close the socket.  output: run: Server is starting... Message received from client: 4+3=7

Alice used a password to create a zip file secret.zip which contains only a secret.txt file. The secret.txt file contains really important information that Alice would like to access. Unfortunately, Alice forgot the password she used to create the zip file. Alice only remembers that the password is a six-digit password.Given the secret.zip file, you are asked to help Alice to recover the password with an implementation in Python.

A Caesar cipher is a simple substitution cipher based on the idea of shifting each letter of the plaintext message a fixed number (called the key) of positions in the alphabet. For example, if the key value is 2, the word "Sourpuss" would be encoded as "Uqwtrwuu." The original message can be recovered by “reencoding" it using the negative of the key. Write a program that can encode and decode Caesar ciphers. The in- put to the program will be a string of plaintext and the value of the key. The output will be an encoded message where each character in the orig- inal message is replaced by shifting it key characters in the Unicode char- acter set. For example, if ch is a character in the string and key is the amount to shift, then the character that replaces ch can be calculated as: chr (ord (ch) + key). 62

Nobody has understood the question thus far.  Please read. It's Java. Write a client program and server program. The server uses a socket connection to allow a client to supply a filename and the server will send the file contents to the client or an error message if the file does not exist. The client will create a new file with the same contents. The client will supply the filename "input.txt" to the server and create as it's output "output.txt". Don't ask the user for these names. The Server sends whatever file the Client requests. Don't put "input.txt" in the Server. The client must get the contents from the Server. It must not read input.txt directly. Do not accept arguments from the command line. One class named Server and one named Client. These must be the ONLY 2 CLASSES

Counting and Looping The program in LoveCS.java prints "I love Computer Science!!" 10 times. Copy it to your directory and compile and run it to see how it works. Then modify it as follows: // LoveCS.java // // // // // Use a while loop to print many messages declaring your passion for computer science **************************** public class LoveCS { public static void main (String [] args) { final int LIMIT = 10; int count = 1; while (count <= LIMIT){ System.out.println("I love Computer Science!!"); count++; } } } Instead of using constant LIMIT, ask the user how many times the message should be printed. You will need to declare a variable to store the user's response and use that variable to control the loop. (Remember that all caps is used only for constants!) Number each line in the output, and add a message at the end of the loop that says how many times the message was printed. So if the user enters 3, your program should print this: 1. 2. 1 I love Computer Science!! 2 I love…

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…

in python. Please include docstring, so I can understand each step to this program. Thanks. you will import the json module. Write a class named NeighborhoodPets that has methods for adding a pet, deleting a pet, searching for the owner of a pet, saving data to a JSON file, loading data from a JSON file, and getting a set of all pet species.  It will only be loading JSON files that it has previously created, so the internal organization of the data is up to you. The init method takes no parameters and initializes all the data members, which must all be private. The add_pet method takes as parameters the name of the pet, the species of the pet, and the name of the pet's owner.  If a pet has the same name as a pet that has already been added, then the function should raise a DuplicateNameError (you'll need to define this exception class). The delete_pet method takes as a parameter the name of the pet and deletes that pet. The get_owner method takes as a parameter the name of the pet and…

Consider the following scenario: you have software that enables you to participate in a surgical operation on a patient in another city from the comfort of your own home computer. Who would be interested in continuing the program once it has been finished. And what type of harm do they want to inflict? Is it conceivable that they will seek to take advantage of your vulnerabilities in order to do you harm? Is it possible that such vulnerabilities might inflict harm even if there is no active, hostile opponent attempting to exploit the situation?
