🔐 File Encryption Tool

📌 Overview

File Encryption Tool is a Python-based GUI application designed to securely encrypt and decrypt files using password-based encryption. The application provides a simple user interface while implementing cybersecurity practices such as secure key generation, password strength validation, and activity monitoring.

The project demonstrates practical implementation of data protection concepts, encryption techniques, and secure logging practices.

🔐 Security Implementation

Password-Based Encryption

The application generates a secure encryption key from the user password using SHA-256 hashing and uses Fernet symmetric encryption for protecting files.

Secure Logging

The application records security events such as:

Sensitive information such as passwords and encryption keys are never stored.

Failed Access Monitoring

Incorrect decryption attempts are recorded for security monitoring:
