Prevent setting critical key components to nullptr when database data is cleared. This can result in a crash due to race condition between threads.
Added a bunch of asserts to detect this problem and if guards to prevent actual crashes.
* Implemented database file hidden attribute preservation on Windows
Implemented database file hidden attribute preservation on Windows by modifying the save function to check the hidden attribute of the original database before saving and then reapply it post-saving if running on Windows so that users can easily store their database in a hidden file without having to re-hide it every time it's modified.
Updated the TestDatabase::testSaveAs() unit test to first verify after the initial save that the database file is not hidden before hiding it then saving again and verifying that it is now hidden.

Attack - KeeShare attachments can be inferred because of attachment de-duplication.
Solution - Prevent de-duplication of normal database entry attachments with those entry attachments synchronized/associated with a KeeShare database. This is done using the KeeShare database UUID injected into the hash calculation of the attachment prior to de-dupe. The attachments themselves are not modified in any way.
--------
Attack - Side channel byte-by-byte inference due to compression de-duplication of data between a KeeShare database and it's parent.
Solution - Generate a random array between 64 and 512 bytes, convert to hex, and store in the database custom data.
--------
Attack vector assumptions:
1. Compression is enabled
2. The attacker has access to a KeeShare database actively syncing with the victim's database
3. The victim's database is unlocked and syncing
4. The attacker can see the exact size of the victim's database after saving, and syncing, the KeeShare database
Thank you to Andrés Fábrega from Cornell University for theorizing and informing us of this attack vector.
* Include check for group as recycle bin directly into the Group::isRecycled() function
* Return the original root group from Database::setRootGroup(...) to force memory management transfer
Closes#5991Closes#3337 - Support fingerprint readers on Linux
Polkit allows for authentication of many means, including fingerprint scanning. Furthermore, a common interface for Quick Unlocking has been implemented, and has been replaced throughout to make implementing other quick unlock strategies easier.
Refactor QuickUnlock to use UUID stored in headers. This is a new feature using the KDBX 4 standard to store a randomly generated UUID in the public headers of the database. This enables identification of KDBX file without relying on path or filename and will eventually support persistent Quick Unlock.
This was noted as a problem in several issues and it finally occurred to me and I traced it to the fact that a timing issue sometimes allowed the file watcher to trigger a "file changed" alert right when saving starts. I fixed this by moving where the mutex lock is made for saving and preventing database reload during a save operation.
* Rename "Database Tags" to "Searches and Tags"
* Separate searching for all entries and resetting the search
* Support selecting multiple tags to search against
* Fix using escaped quotes in search terms
* Make tag searching more precise
* Support `is:expired-#` to search for entries expiring within # days. Exclude recycled entries from expired search.
* Don't list tags from entries that are recycled
* Force hide tag auto-completion menu when tag editing widget is hidden. On rare occasions the focus out signal is not called when the tag view is hidden (entry edit is closed), this resolves that problem.
* Remove spaces from before and after tags to prevent seemingly duplicate tags from being created.
* Also fix some awkward signal/slot dances that were setup over time with the entry view and preview widget.
Allow changing tags for multiple entries through context menu
* Closes#8277 - show context menu with currently available tags in database and checks those that are set on one or more selected entries. When a tag is selected it is either set or unset on all entries depending on its checked state.
* Add ability to save searches and recall them from the "Searches and Tags" view
* Add ability to remove a tag from all entries from the "Searches and Tags" view
* Cleanup tag handling and widgets
* show the tags in the entry preview
* allow searching by tag
* add a sidebar listing the tags in the database
* filter entries by tag on click
* Introduce a new TagsEdit widget that provides pill aesthetics, fast removal functionality and autocompletion
* add tests for the tags feature
* introduce the "is" tag for searching. Support for weak passwords and expired added.
Shows a warning when trying to open with a newer minor version than what is currently supported.
We always try to save with the lowest KDBX version possible for maximum compatibility.
- Default backupFilePath is '{DB_FILENAME}.old.kdbx' to conform to existing standards
- Implement backupPathPattern tests.
- Show tooltip on how to format database backup location text field.
* Closes#6335
* Modify application settings presentation to allow for alternative saving strategies
* Transition Database::save calls to using flags to control saving behavior. Reduces boolean flags on function call.
* Made direct write save option a local setting to prevent unintentional carry over between platforms.
* Introduced in #6438, modified signal is not blocked at the Database level when emitting is blocked. This causes infinite saving to occur when Always Save After Every Change is enabled.
* Fix#5107
* Change setting for non-data changes to Auto save on database lock (or not) instead of marking modified.
* When enabled, database will be auto-saved if there are only non-data changes, but will not prompt the user if saving has failed.
* When disabled, database will not auto-save if there are only non-data changes (same behavior as 2.5 and below) and will not mark the database dirty.
Definitions:
* Database Key - Cryptographic hash used to perform encrypt/decrypt of the database.
* Database Credentials - User facing term to refer to the collection of Password, Key File, and/or Hardware Key used to derive the Database Key.
Changes:
* Remove the term "master" and "key" from the user's lexicon and clarify the code base based on the definitions above.
* Clean up wording in the UI to be clearer to the end user.
* Saving a database in unsafe mode retains the existing permissions on the kdbx file
* New databases (save as, save backup, new database) and new key files are saved with 0600 permissions (user read/write), fixes#2575
* Fix issues when Config options were renamed
* Fix compile issues when using clang 10
* Rearrange database menu icons and import database menu icons
* Set minimum size of MainWindow to 800 to prevent search bar from hiding
* Fix not saving password generator options when closing the standalone generator
* Add headers to health check reports
* Don't show hidden content dots when notes are hidden but empty.
* Fix saving new database files in SMB shares on Windows, fixes#4809
* Gracefully handle duplicate attachments :
Instead of bailing out with an error, prepend a random string to the name of duplicate attachment records. This prevents data loss from other programs that mishandled KDBX XML writing. Fixes#2493
* Properly handle blocked import of signed KeeShare database, fixes#4413
- Unify widget layouts and margins
- Fix tab order on a bunch of widgets
- Fix broken entry/group edit form layout and replace with grid layout
- Rearrange some settings for better logical grouping
- Fix some settings checkboxes not being enabled/disabled on load
- Fix "General" settings tab scrolling
- Rename "Root" group to "Passwords"
- Update demo.kdbx accordingly and redownload favicons
- Change entry path display to use slash separators
- Reduce Medium and Large icon sizes slightly
Introduce a third unsorted status that shows entries in the order they occur in the KDBX file.
* Add keyboard shortcut Ctrl+Alt+Up/Down to move entries up and down in sort order
* Add entry context menu icons to achieve movement up/down
* Only show menu icons when in natural sort order
* Add Material Design icons for moving up/down
* Add feature to track non-data changes and force a save on exit to ensure they are not lost when locking a database. This allows users to make entry movements and group expand/collapse operations and not lose that state.
Remove saveas
* Significantly improve user experience when using hardware keys on databases in both GUI and CLI modes. Prevent locking up the YubiKey USB interface for prolonged periods of time. Allows for other apps to use the key concurrently with KeePassXC.
* Improve messages displayed to user when finding keys and when user interaction is required. Output specific error messages when handling hardware keys during database read/write.
* Only poll for keys when previously used or upon user request. Prevent continuously polling keys when accessing the UI such as switching tabs and minimize/maximize.
* Add support for using multiple hardware keys simultaneously. Keys are identified by their serial number which prevents using the wrong key during open and save operations.

* Fix#3790, shares now use the standard FileWatcher class to detect remote file changes using checksums and file system triggers.
* Fix#3895, macOS file selection no longer hangs the app.
* Restore saving of KeeShare settings accidentally removed by 596d2cf
* Wrap key transformation in AsyncTask when reading a database. Significantly reduces user interface lockup.
* Replace root group with new group instead of deleting the pointer (fulfills member validity promise).
* Add saving mutex to database class to prevent re-entrant saving
* Prevent saving multiple times to the same file if the database is not marked as modified
* Prevent locking the database while saving. This also prevents closing the application and database tab while saving.
* FileWatcher: only perform async checksum calculations when triggered by timer (prevents random GUI freezes)
* Re-attempt database lock when requested during save operation
* Prevent database tabs from closing before all databases are locked on quit
The challenge-response key buffer is explicitly cleared
before the key transformation if no such key is configured
to ensure one is never injected into the hash even if the
database had a challenge-response key previously.
This patch also adds extensive tests for verifying that a
key change will not add any expired key material to the hash.
Fixes#4146
* Mark the database as clean after fully completing the file save operation INSTEAD of when merely writing the database to a file.
* Stop the modified timer when marking the database as clean, this prevents latent erroneous modified signals from being emitted.
* Do not restart the modified timer after a new change is detected while it is still running.
The transformed secrets were stored in normal QByteArrays,
which are at risk of being swapped out. We now use secure
PasswordKey objects instead. There are still a few areas
where QByteArrays are used for storing secrets, but since
they are all temporary, they are less critical. It may be
worth hunting those down as well, though.
When we lock a database, we reset the database pointer to
free its resources. Since various other widgets besides the
DatabaseWidget hold references to the shared pointer object,
however, it cannot be guaranteed that the actual database
object will be freed right away. This patch adds a releaseData()
method which is called upon database lock to ensure all
residual data is cleared without having to rely on the actual
database object being cleaned up.
* Fix#3699
Reduce file watch hashing of open database files from every second to every 30 seconds. Additionally, only hash the first 1024 bytes of the database file. This is valid since most of the header and the entire encrypted portion are changed significantly on every save.
* Fix#3506
* Fix#2389
* Fix#2536
* Fix#2230
Every database that has been opened now watch's it's own file. This allows the database class to manage file changes and detect fail conditions during saving. Additionally, all stakeholders of the database can listen for the database file changed notification and respond accordingly.
Performed significant cleanup of the autoreload code within DatabaseWidget. Fixed several issues with handling changes due to merging, not merging, and other scenarios while reloading.
Prevent database saves to the same file if there are changes on disk that have not been merged with the open database.
Fixes#3365
Add prompt to delete the recycle bin when disabling it. If the user chooses not to delete it, the recycle bin will be suffixed with "(old)" and the icon changed to the default group icon.
Also moved recycle bin creation within the database class where it belongs.
The CLI now contains an "import" command that creates a new database from the specified XML export. The new database is in kdbx 4 format, and does not currently accept a keyfile in database creation.
This change is required to create new databases from XML backups.
Fixes#2458
* Fix#3407
* Read-only files now disable auto-save and show as modified correctly. This allows the GUI to prompt to "save-as" instead of silently discarding changes when the read-only database is locked or closed.
* Fixes#3126
* Limit autocompletion to the top ten used usernames
- Load common usernames when database is opened
- Transition from QLineEdit to QComboBox for usernames
- Dropdown menu of the combobox lets user choose a common username
- Common usernames are autocompleted via inline completion
- Common usernames are sorted by frequency (first) and name (second)
