Changelog - AESCrypt Argon 5.0
[5.0] - 17-11-2024

Additions and Improvements:

Graphical User Interface (GUI) Refactoring:

  • The interface has been enhanced with a cleaner and more functional design.
  • The window size has been adjusted to 675x350, and the window is now non-resizable.
  • Colored buttons have been added for encryption (green) and decryption (red) actions.
  • Tooltips have been included for better user experience.
  • A dark theme has been applied to the interface, with colors and design adjusted for better readability and aesthetics.

Encryption and Decryption:

  • The encryption and decryption process remains secure and efficient, utilizing AES-256 in GCM mode and Argon2 as the key derivation function.
  • HMAC-SHA256 has been implemented to ensure data integrity during the encryption process.
  • Random padding has been added to the encrypted data to mask the original file size.

Password Generation Function:

  • A new feature allows users to generate a random 32-character password, including uppercase and lowercase letters, numbers, and symbols.
  • The generated password is automatically inserted into the password field in the interface (shown as asterisks: *********).

Secure File Deletion:

  • The secure file deletion function has been enhanced to ensure that sensitive data is overwritten before removal.
  • The file is overwritten with random data before deletion, following recommended security practices.

Exception Handling:

  • The software now correctly handles incorrect password exceptions during decryption without exposing internal failure details (HMAC error).
  • Error messages have been improved to be more informative and clearer to the user.
  • Protection against unexpected failures and proper notifications to the user when something goes wrong.

Improvement in Encryption and Decryption Flow with Threads:

  • The encryption and decryption process has been moved to separate threads, allowing the graphical interface to remain responsive during heavy operations.
  • The progress bar has been adjusted to correctly reflect the status of each operation (100% upon completion).

Success and Error Messages:

  • Added success messages to notify the user when a file has been successfully encrypted or decrypted.
  • More detailed error messages with specific handling for incorrect passwords during decryption.

Input Validation:

  • Input validation has been improved to ensure that both the file path and password are correctly provided before starting the encryption or decryption process.
  • The validation of absolute file paths has been removed, as it caused issues in some scenarios.

Bug Fixes:

File Path Issue Fix:

  • The software now handles the file path correctly during encryption and decryption.
  • Removed the validation of absolute file paths to avoid failures when reading the file path.

Progress Bar Issue Fix:

  • The progress bar now correctly reflects the status of the encryption/decryption process.
  • Fixed erratic behavior of the progress bar, which would restart in some cases.

Incorrect Password Issue Fix:

  • The incorrect password error is now handled appropriately without exposing internal HMAC failure details.
  • The software no longer displays technical error details (such as the HMAC error) to the end user.

Other Improvements:

Code and Architecture Enhancement:

  • Refactored the code to improve readability and maintainability.
  • Improved the flow of encryption and decryption functions, making the process more robust and easier to follow.

User Interface Adjustments:

  • All text in the interface has been translated to English.
  • The design has been adjusted to provide a more intuitive user experience.

Other Minor Improvements:

  • Enhanced error handling and user feedback.
  • Style and layout adjustments to make the interface more aesthetically pleasing and organized.
