Overview

This release of FileEncryptor introduces significant updates and enhancements, focusing on improving the handling of large files and the security of the encryption process. The application now utilizes AES-GCM for encryption, providing a more robust and efficient method suitable for large files.

New Features

  • AES-GCM Encryption: Transitioned from Fernet to AES-GCM for file encryption and decryption, allowing for efficient processing of large files.
  • Chunked File Processing: Implemented chunked processing for large files to prevent memory overload and application crashes.
  • Progress Bar: Added a progress bar during encryption and decryption processes for better user feedback, especially useful for large files.

Enhancements

  • Key Derivation: Improved the key derivation process to use PBKDF2 with SHA-256, enhancing the security of the generated keys.
  • Increased Iterations: The number of iterations in the key derivation function has been increased to 750,000, significantly strengthening the resistance against brute-force attacks.
  • Nonce Management: Each encryption operation now uses a unique nonce, in line with AES-GCM requirements, to enhance security.

Bug Fixes

  • Key Size Issue: Resolved an issue where the key size was incompatible with AES-GCM requirements.
  • Error Handling: Improved error handling and messaging throughout the application.

Breaking Changes

  • Key Incompatibility: Due to the switch to AES-GCM, keys generated in previous versions are not compatible with this release. Users will need to regenerate keys.

Instructions

  • For encryption: ./FileEncryptor encrypt <file_path>
  • For decryption: ./FileEncryptor decrypt <file_path>
