Abstract

In the digital communication era, ensuring the security and confidentiality of sensitive information is crucial. This project proposes a robust encryption scheme that combines Advanced Encryption Standard (AES) with Visual Cryptography (VC) to achieve high security, reliability, and efficiency.The application allows users to encrypt and decrypt files through a user-friendly GUI built with Python's Tkinter library. Users provide a key to XOR each byte of the file's content for encryption, and the process is reversed for decryption. The tool includes comprehensive error handling to manage file access permissions, key validation, and other potential issues. Designed for users with varying technical expertise, this solution enhances data security by protecting sensitive information from unauthorized access while ensuring data integrity during storage and transmission.
