This issue previously caused parent databases to be marked as modified on unlock. This was because of the new protections against byte-by-byte side channel attacks adds a randomized string to the database custom data. We should never be merging database custom data with keeshare or imports since we are merging groups only.
Also prevent overwrite of auto-generated custom data fields, Last Modified and Random Slug.
* Restrict access to changing DACL's after the process is started. This prevents the creator of the keepassxc.exe process from simply adding the permission to read memory back to the DACL list.
* Verified using System Informer.
* This removes the application setting to require typing the password in again even though it is visible.
* Removed automatic password repeat when the password is made visible on changing.
* Fixes#10455
* Fixes#10432
* Fixes#10415
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.
* Closes#7545 - Support 1Password 1PUX import format based on https://support.1password.com/1pux-format/
* Closes#8367 - Support Bitwarden JSON import format (both unencrypted and encrypted) based on https://bitwarden.com/help/encrypted-export/
* Fixes#9577 - OPVault import when fields have the same name or type
* Introduce the import wizard to handle all import tasks (CSV, KDBX1, OPVault, 1PUX, JSON)
* Clean up CSV parser code to make it much more efficient and easier to read
* Combine all importer tests (except CSV) into one test file
* 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
* Previously our base style sheet added roughly 20px of margin to the top and bottom of all QGroupBox. This caused visual errors where that margin was not needed/desired.
* Transferred padding to the specific layouts instead where it belongs.
The private exponent d may be negative in which case an additional pad
byte is needed. Otherwise ssh-agent fails to load the key.

Refactors the Passkey implementation to include more checks and a structure that is more aligned with the official specification.
Notable changes:
- _BrowserService_ no longer does the checks by itself. A new class _BrowserPasskeysClient_ constructs the relevant objects, acting as a client. _BrowserService_ only acts as a bridge between the client and _BrowserPasskeys_ (authenticator) and calls the relevant popups for user interaction.
- A new helper class _PasskeyUtils_ includes the actual checks and parses the objects.
- _BrowserPasskeys_ is pretty much intact, but some functions have been moved to PasskeyUtils.
- Fixes Ed25519 encoding in _BrowserCBOR_.
- Adds new error messages.
- User confirmation for Passkey retrieval is also asked even if `discouraged` is used. This goes against the specification, but currently there's no other way to verify the user.
- `cross-platform` is also accepted for compatibility. This could be removed if there's a potential issue with it.
- Extension data is now handled correctly during Authentication.
- Allowed and excluded credentials are now handled correctly.
- `KPEX_PASSKEY_GENERATED_USER_ID` is renamed to `KPEX_PASSKEY_CREDENTIAL_ID`
- Adds a new option "Allow localhost with Passkeys" to Browser Integration -> Advanced tab. By default it's not allowed to access HTTP sites, but `http://localhost` can be allowed for debugging and testing purposes for local servers.
- Add tag `Passkey` to a Passkey entry, or an entry with an imported Passkey.
Fixes#10287.
Closes#2689
The design of the respective code is loosely based on KDE's KActionCollection. The ActionCollection manages all actions that can be shortcut configured. These actions are then exposed in the config and a user can assign a different shortcut.
Actions inside the MainWindow have been added to the ActionCollection.

* Fix#9847 - don't provide TOTP values if settings are blank or completely wrong
* Fix#6838 - don't reset the ui when creating a new entry and applying TOTP to it
* Move totp source into the core folder
* Set default value of DatabasePasswordMinimumQuality to 3 (do not accept a master password that is less than Good)
* Add custom message box button "Continue with weak password"
* Entry: re-parent before adding to new group
Adding the Entry to the Group will emit signals about the action.
Present the object with the correct parent already.
* fdosecrets: Item::Create() can fail
If an entry cannot be registered on DBus, Item::Create() will return a
nullptr. Basically, this can only happen if there is already an item
with the same UUID in the collection. The only viable option here is to
ignore the new entry.
* Merger: prevent duplicate entry when merging histories
If the source entry is newer, a copy of the entry is made. But before
moving the merged entry to the target group, it must be removed.
Otherwise there will be briefly two entries with the same UUID
in the same group/database.
Even though this is only the case during the transaction, it can still
be observed because the operations emit signals. A notable problem is
the fdosecrets feature that relies on the uniqueness of the UUID or will
otherwise run into problems because the UUID is used as part of the DBus
path.
Botan::secure_scrub_memory -> defined in mem_ops.h
Botan::secure_vector -> defined in secmem.h
The reason only including secmem.h worked in previous (<3.0) versions of
Botan was because secmem.h included mem_ops.h. This is no longer the
case since commit

Fixes#10038
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.
Keepassxc saves application state at XDG_CACHE_HOME which can be cleared on some systems periodicly.
This is not desireable as app state like window size is not consistent when openning the app.
To avoid this this commit is switching the path to XDG_STATE_HOME which is more fitting based on the freedesktop basedir spec (https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html), this will allow to prevent state file deletion as well.
Resolves#9738
* Fix#7892 - Pressing escape when the quick unlock prompt is shown will now go back to the main unlock dialog view.
* Fix#9030 - Quick unlock will be automatically invoked in the unlock dialog upon being shown.
* Fix#9554 - Quick unlock application setting will be updated every time the settings widget is shown instead of just on first launch.
* Show warning that quick unlock is not enabled if user cancels Windows Hello prompt. This should limit people thinking there is a security issue. Also improve documentation describing this behavior.
* Disable quick unlock in gui tests
