The purpose of this project is to have a desktop application that enables users to encrypt or decrypt "secret phrases" using a simple Caesar Cipher algorithm. This project was undertaken as a personal project to enhance my Java programming skills and delve into cryptography and security concepts like secure password storage and user authentication. This is my first project upload on Github as well! I enjoyed this project and had a ton of fun creating it and learning new aspects of Java programming.
| Feature | Description | Class Location |
|---|---|---|
| GUI | User interaction through Java Swing GUI components | MainWindow.java |
| RegistrationFrame.java | ||
| LoginFrame.java | ||
| DecryptionPanel.java | ||
| EncryptionPanel.java | ||
| Encryption Algorithm | Caesar Cipher based encryption for user phrases | CeasarEncryption.java |
| Decryption Algorithm | Caesar Cipher based decryption for user phrases | CeasarDecryption.java |
| User Authentication | Basic user authentication to control application access | MainWindow.java |
| Registration | New user registration for access to the application | RegistrationFrame.java |
| Hashing of User Passwords | Usage of SHA-256 for password hashing | CeasarUser.java |
| Use of a Database | JDBC connection to MySQL to store user info and phrases | CeasarUserDAO.java |
| Various Security Measures | Parameterized SQL queries to prevent SQL injection | CeasarUser.java |
| CeasarUserDAO.java |
| Feature | Reasoning |
|---|---|
| Unique views for individual users | Difficulty in displaying phrases based on user ID |
| Salting Passwords | Not implemented; essential for commercial use standards |
| Ability to update phrases | Considered redundant as secret phrases are typically fixed |
| Locking mechanisms for login | Lack of implementation awareness for locking mechanisms |
- JDBC for database connectivity and interactions.
- Usage of Parameterized statements for secure SQL queries.
- Working with Java Swing components (JFrames, JTables, JTextAreas, etc.).
- Event Listeners/Action Listeners for UI functionality.
- Cryptography using a Caesar Cipher algorithm for encryption/decryption.
- Creation of a Java Executable JAR file with a desktop shortcut.
- Embracing Object-Oriented Programming (OOP) principles:
- Abstraction for hiding functionalities.
- Encapsulation for data and behavior confinement.
- Modular coding using classes.
- Security Best Practices such as password hashing and SQL query security.
- Database Design
- Enforcing Data Integrity using entity integrity and referential integrity.
- Writing SQL queries (SELECT, UPDATE, INSERT).

HERE IS A BRIEF OVERVIEW OF THE PROJECT STRUCTURE
STEPS TO RUN THE APPLICATION
- Gather all the java files for this repository and download them onto your device.
- Go into your IDE and create a new Java package using the files from the repository.
- Make your MySQl database using a similar schema to mine. Look at the SQL files provided in the repository.
- Change necessary parts of the source code such as the JDBC class information (make sure it pertains to your own database)
- Once everything is connected, test the application in your IDE.
- Now, create a executeble JAR file for the application on your device in your IDE.
- After the JAR file is created you can go to its file path on your device, right click it, and create a shortcut for it.
