FileEncryptor

This File Encryption Program is a Python-based tool designed to securely encrypt and decrypt large files using a password-derived key. It employs robust cryptographic methods, including PBKDF2 with SHA-256 for key derivation and AES-GCM for encryption, making it suitable for processing large files efficiently.

Features

AES-GCM Encryption: Utilizes AES-GCM for secure and efficient encryption, suitable for large files.
Password-Based Encryption: Generates a secure encryption key based on a user-provided password.
File Encryption and Decryption: Encrypts files with a .enc extension and decrypts them back to their original state.
Chunked File Processing: Processes files in chunks to efficiently handle large files without excessive memory usage.
Progress Bar: Displays a progress bar during encryption and decryption processes for better user feedback.
Secure Key Management: Securely stores the encryption key in an encrypted file, ensuring access only for the password holder.
