E-Books →Network and Web Security Encryption and Decryption

**Introduction**: In this book, readers will become familiar with the functioning of each section of the program. Explanations accompanied by figures are provided to assist in better understanding.
**Program Design Objectives**:
1. Facilitate text messaging among clients within a local network.
2. Minimize network traffic (exchange minimum data between network lines).
3. Utilize encryption and decryption algorithms to prevent hacker intrusions.
4. Avoid the use of a database.
**Brief Explanation**: This program is designed to facilitate text communication among members of a network to prevent unnecessary traffic on the website, and allow file transfer without sharing client files.
**Abstract**: Due to the need of network users to exchange information electronically, various software applications are available in the market. Among the concerns, factors such as efficiency, security, and reliability are highly significant. Security, the main focus of this project, involves becoming familiar with various encryption algorithms to prevent hacker intrusions.
