Computer Science C programming Develop a proxy HTTP server that can accept HTTP requests from clients and convert them to HTTPS request to the web server. The HTTP request can be filtered based on an access control list. The requests can be generated by any web client, such as the curl command or a web browser. the proxy converts plain text HTTP requests from a client to HTTPS requests and then returns the responses to the client. Main objective is to create a proxy HTTP server that converts cleartext HTTP requests from clients to HTTPS requests to servers and vice versa for the responsesresponses.
Using Java Programming Language (Java Socket /TCP Programming) Please make a simple messaging program that will allow users to send private messages to other users (not the server). All the users have their usernames and passwords stored in an XML file Users can only send messages to online users Messages to offline users will be stored in a separate XML file

Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads
The URL Connection class can be used to read and write data to the specified resource referred by the ReadableByteChannel Select one: True False
Tasks: Part A: Develop a UDP/IP server program in java that waits for clients to server. The server responds to the client with one of the following based on client’s request: Export secret key generated using KeyGenerator Export Text and Message Digest Export Text and Digital Signature Send original text for the encrypted text received from client Part B: Develop a UDP/IP client program that make request secret key, Message Digest, Digital Signature and original text by sending the encrypted text to server program developed (in Part A). This program will display the various objects received from server on its console.

Q.7. Design and implement a client/ Multi-threaded Server Chat application where a set of clients are able to send their request to the Multithreaded Server. In this application, messages that are exchanged between client and server, must be encrypted using AES encryption algorithm. After receiving the message, each party (client or server) perform decryption operation and show the content of message on the terminal.

In which of the following applications, UDP is a suitable transport layerprotocol? (a)In SMTP, a user can send a long e-mail message, which may includemultimedia. When a user sends a message, the recipient does not expectto receive a response quickly. (b)A user needs to download a very large text file from the internet. Theuser doesn’t want part of the file to be missing or corrupted when he/sheopens the file. The delay created between the delivery of the parts arenot an overriding concern for him. (c)In DNS, a client needs to send a short request to a server and to receive a quick response from it. The request and response can each fit in one userdatagram.
