ABSTRACT
Several network systems are built to communicate with one
another as well as made available through service-oriented architectures. In
this project, the client server architecture is used to develop a chat
application. Firstly a chat application is created for both Client and Server
which is based on Transmission Control Protocol (TCP) where TCP is connection
oriented protocol and is a reliable connection protocol. As security is the key
factor while communicating over a network, so in this project, MySQL SSL
protocol and hash function was used for the Database based on a numbers of
benefits. The hash values of the real password and the random generated number
(salt) is stored in the database. The original password is not stored on the
system, making cracking of password much harder....
CHAPTER ONE
1.1 INTRODUCTION
Several network systems are built to communicate with one
another and are made available through service-oriented architectures. In this
project, we use the client server architecture to develop a secured
Client-Server chat application. A chat application is created based on
Transmission Control Protocol (TCP) where TCP is connection oriented protocol
and in the end, multithreading is used to develop the application.
A client-server chat application consists of a Chat Client
and a Chat Server and there exists a two way communication between them. Here,
Message Processor is used to interpret message from the user, Message
Interpreter is used to extract and pass the received message. Message Maker is
used to construct back the message and Client Manager is used to maintain the
clients list which the sender and receiver at both sides use to interact with
each other.
