Encryption and Decryption with JavaScript

The Data Encryption and Decryption Tool is a web and cross-platform desktop application developed using JavaScript and Electron that provides secure encryption and decryption functionalities using the AES-CBC (Advanced Encryption Standard - Cipher Block Chaining) algorithm. It supports localization using i18next for multi-language support, enhancing usability across different regions. The application ensures data security by implementing PBKDF2 (Password-Based Key Derivation Function 2) for key derivation and AES-CBC for symmetric encryption.

Overview

The Data Encryption and Decryption Tool is a web and desktop application developed using JavaScript and Electron that provides secure encryption and decryption functionalities using the AES-CBC (Advanced Encryption Standard - Cipher Block Chaining) algorithm. It supports localization using i18next for multi-language support, enhancing usability across different regions. The application ensures data security by implementing PBKDF2 (Password-Based Key Derivation Function 2) for key derivation and AES-CBC for symmetric encryption.

Features

• Encryption and Decryption: Enables users to encrypt plain text messages and decrypt encrypted messages securely using AES-CBC.
• Secure Key Management: Implements PBKDF2 for deriving encryption keys from passwords, enhancing security against brute-force attacks.
• Localization: Supports multiple languages through i18next, allowing users to interact with the application in their preferred language.
• Responsive Design: Built with a responsive design using HTML5, CSS3 (SCSS), and JavaScript, ensuring compatibility across desktop and mobile devices.
• User Interface: Provides an intuitive interface with interactive elements such as sliders for dark/light mode selection and language dropdown for localization.
• Cross-Platform: Available for Windows, macOS, and Linux platforms.
• Desktop Application: Run the application by double-clicking the executable file, no need to open HTML files in browsers.
• Integration: Designed to integrate seamlessly into existing systems, demonstrating interoperability and modularity.
