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.
* 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
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.
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
Fixes#6190
Remove the advanced settings checkbox and replace with a dedicated tab widget interface to toggle between basic and advanced encryption settings.
Add a new propery autosaveDelay in Metadata of the db.
The property is saved in customData to not affect database structure as this setting is unique to keepasxc.
The propery sets delay to wait since last modification before saving.

* Fixes#9390
* Create one QCollator per entry view instead of creating one on every sort request. This greatly improves the speed of sorting and displaying entries.
* Rewrite recursive multiple placeholder replacement to use QRegularExpression
* SymmetricCipher: Fix Botan 3 build
Botan commit 819cf8fe6278a19b8266f449228f02fc28a4f784 changed
Botan::Cipher_Dir to be a scoped enumeration, so the users
must be adapted.
This change causes no issues with Botan 2 because normal
enumeration values can also be referred to the same way
scoped enumeration values are accessed.
* Auto detect Botan3
* AsyncTask: Do not use `std::result_of`
`std::result_of` was deprecated in C++17 and then it was
subsequently removed in C++20. One could use `std::invoke_result_t`,
but let Qt figure out the return type instead.
* Collapse Botan2 and Botan3 find package into one
* Update COPYING

* Add configuration to hide TOTP in preview widget (shown by default).
* Retain the visibility of TOTP and other fields when the same entry remains selected in the preview panel.
* Fix disconnecting signals when switch entries / groups. This likely is going to fix crashes because we were compounding signals when focusing in on the main window.
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.
