Update 3.1

IMPORTANT NOTES

Windows users

The Windows installers are signed with an open source self-certificate, so Windows might do... you know, Windows shenanigans and complain about the app's trustworthiness. Of course, it's up to you whether to trust them or build them yourself. (Can't really afford a code signing certificate, sorry!)

Other operating systems

Since the app works with any OS, but the installers are only for Windows and Linux, I included the portable versions (which do not come with a bundled java runtime), with their respective signature.

PGP signatures and checksums

The .asc files contain OpenPGP signatures. If desired, these can be verified with any tool that can read them, I suggest Kleopatra.
You can easily find my public key (using the mail address listed below) on keys.openpgp.org, by running gpg --auto-key-locate keyserver --locate-keys user@example.com or simply uploaded as a release file.

3.1 PATCH HISTORY

Patch 3.1.2 (March 16, 2026)

This update focuses on security and reliability first, while also polishing a few UX details that were still rough around the edges. The encryption flow has been redesigned to support safer key handling and future-proof account management, and several UI areas were improved to behave more consistently across different screen sizes.
Please note that the new internal encryption technique could be described as "foreshadowing".

Features

• Improved overall account protection with a new internal encryption workflow.
• Enhanced general handling of user actions and all under-the-hood stuff.
• Made all the application resizable, beside EULA.
• Improved save popup behavior and visibility.
• Added country flags to the language selector for clearer localization settings.
• Refined password field controls for clearer and more consistent UI behavior.
• Improved loading animations and error handling across the application.
• Included various stability and compatibility improvements through dependency and configuration updates.

Code

• Migrated account encryption to a DEK-based model, with KEK support and HKDF/Argon2-driven key derivation flow.
• Implemented full-account encryption refactoring across Account, AES, UserPreferences, and related security classes.
• Refactored AccountRepository synchronization logic to avoid inconsistent internal states.
• Improved locale persistence by adding a serialization-transparent SupportedLocale enum.
• Refactored singleton infrastructure again, consolidating behavior into an abstract singleton base and improving lifecycle handling.
• Introduced and integrated the new CustomPopup component in lib, replacing previous popup content handling.
• Refined controller and FXML structure (including AbstractController, TabManager, and package/layout moves) for cleaner separation.
• Improved Logger formatting support and updated Transaction naming/identifier handling.
• Enhanced memory reservation logic to account for internal overhead.
• Refactored password field controls to use skin-based approach for lighter and clearer implementation.
• Enhanced LoadingAnimation with improved future handling and error validation.
• Expanded and revised tests (including new TestUserPreferences and reorganized test packages) to cover security, singleton lifecycle, repository behavior, and transactions more thoroughly.
• Updated dependencies/modules and related Gradle configuration for better cross-module compatibility.

Patch 3.1.1 (December 12, 2025)

A lot of under-the-hood changes have been made to the application for better account management while enhancing code organization, maintainability and allowing for unit testing. This also brings smaller UI additions and fixes.

Features

• Added playful prompts for empty fields
• Fixed password suggestions in packaged version
• Improved loading animations and save popup visibility
• Various bug fixes and stability improvements

Code

• Merged AbstractViewController into AbstractController
• Introduced animation-dedicated classes while refactoring their handling
• Implemented a unified singleton pattern
• Refactored IOManager to use AccountRepository, with a CRUD-like implementation
• Added TransactionManager for transactional operations
• Enhanced SecurityVersion with memory reservation
• Improved error handling and logging throughout
• Added unit tests for AES, Account, AccountRepository, transactions, and singleton lifecycle
• Bumped Gradle and dependencies to latest versions

Patch 3.1.0 (October 17, 2025)

The entire UI has been redesigned and rewritten to provide a more comfortable and intuitive user experience while maintaining a modern look and feel.
The encrypter and decrypter have been unified into a single page - the Manager - which now features a list-based layout instead of the bulky combo box previously used for account selection. This new design introduces a tab-oriented interface, allowing users to have multiple editors open simultaneously.

Also, the following shortcuts have been added:

• Ctrl + Q/E: Scroll tabs left/right
• Ctrl + W: Close current tab
• Ctrl + T: Go to add tab

This adds up to the pre-existing Return shortcut (helps to navigate trough text fields).

Features

• Implemented search functionality in ManagerController.
• Added auto-completion feature and multiple keyboard shortcuts.
• Implemented data backup functionality with a streamlined process.
• Implemented autosave popup for better user feedback.
• Added effects and improved UI/UX consistency
• Added localization updates to improve clarity and consistency.

Code

• Bumped Java and JavaFX version to 25 and Gradle to version 9.1, improving Gradle configuration and JVM arguments.
• Added PasswordInputControl interface for consistent password field behavior.
• Refactored application structure:
  • Consolidated IOManager and ObservableResourceFactory into singletons.
  • Later improved singleton logic using a class-mapped approach.
• Merged AppManager into App for a cleaner architecture.
• Refactored AppManager, ManagerController, UserPreferences, and IOManager for readability, better property handling, and maintainability.
• Enhanced logging across FXML loading and controllers for consistency and clarity.
• Introduced TabManager delegate for encapsulation and better controller separation.
• Refactored security handling:
  • Moved key derivation functions into SecurityVersion, to emphasize their strict bound
  • Updated password encryption/decryption logic.
• Refactored code to use final modifiers for local variables to improve clarity and performance.
• Enhanced asynchronous account list handling using CompletableFuture.
• Cleaned up whitespace across files and streamlined password handling (e.g., stripping input).
