* Support NFC readers for hardware tokens using PC/SC
This requires a new library dependency: PCSC.
The PCSC library provides methods to access smartcards. On Linux, the third-party pcsc-lite package is used. On Windows, the native Windows API (Winscard.dll) is used. On Mac OSX, the native OSX API (framework-PCSC) is used.
* Split hardware key access into multiple classes to handle different methods of communicating with the keys.
* Since the Yubikey can now be a wireless token as well, the verb "plug in" was replaced with a more
generic "interface with". This shall indicate that the user has to present their token to the reader, or plug it in via USB.
* Add PC/SC interface for YubiKey challenge-response
This new interface uses the PC/SC protocol and API
instead of the USB protocol via ykpers. Many YubiKeys expose their functionality as a CCID device, which can be interfaced with using PC/SC. This is especially useful for NFC-only or NFC-capable Yubikeys, when they are used together with a PC/SC compliant NFC reader device.
Although many (not all) Yubikeys expose their CCID functionality over their own USB connection as well, the HMAC-SHA1 functionality is often locked in this mode, as it requires eg. a touch on the gold button. When accessing the CCID functionality wirelessly via NFC (like this code can do using a reader), then the user interaction is to present the key to the reader.
This implementation has been tested on Linux using pcsc-lite, Windows using the native Winscard.dll library, and Mac OSX using the native PCSC-framework library.
* Remove PC/SC ATR whitelist, instead scan for AIDs
Before, a whitelist of ATR codes (answer to reset, hardware-specific)
was used to scan for compatible (Yubi)Keys.
Now, every connected smartcard is scanned for AIDs (applet identifier),
which are known to implement the HMAC-SHA1 protocol.
This enables the support of currently unknown or unreleased hardware.

The HEX button automatically unselects `selectBoxLower` therefore there is no need to also add `ghijklmnopqrstuvwxyz` in the excluded characters text field.
* Closes#2322
* Show locked databases in tabbed interface in unlock dialog for browser and auto-type workflows.
* Make the DatabaseOpenDialog window Application-Modal so that it blocks input to the main UI when the dialog is open. This reduces corner cases by avoiding the possibility of databases getting closed or unlocked
behind the open dialog.
Externally opened attachments are now lifecycle-managed properly.
The temporary files are created with stricter permissions and entirely
random names (except for the file extension) to prevent meta data leakage.
When the database is closed, the files are overwritten with random
data and are also more reliably deleted than before.
Changes to the temporary files are monitored and the user is asked
if they want to save the changes back to the database (fixes#3130).
KeePassXC does not keep a lock on any of the temporary files, resolving
long-standing issues with applications such as Adobe Acrobat on Windows
(fixes#5950, fixes#5839).
Internally, attachments are copied less. The EntryAttachmentsWidget
now only references EntryAttachments instead of owning a separate copy
(which used to not be cleared properly under certain circumstances).
* Use hash based storage for last used directories instead of a key/value for each type
* Explicitly declare certain operations as sensitive and follow the "Remember Last Database" setting for those.
* Introduce database backup directory location (close#6619)
* Closes#4986 - Allow deleting entries from the reports view
* Closes#4533 - Exclude & delete multiple entries in a report
* Also allow deleting selected entries using the delete key
* Introduce GuiTools namespace to collect shared GUI prompts and actions
* Add functionality to HIBP report to mirror health check report

The MinimizeAfterUnlock setting added in #3439 closes the main window
after unlock. However, when the unlock is triggered through
KeePassXC-Browser, a password dialog is shown on top of the main window
and the main window remains open after the unlock. This is fixed
in this commit.
* Fix#505 - always show the search bar when the search keyboard shortcut is pressed. If the toolbar is in overflow, the toolbar will be expanded automatically and search focused. If the toolbar is hidden it will be shown and expanded if necessary. When searching is canceled or the down arrow is pressed (to select the first entry) the toolbar will be set back to it's previous configuration.
Selected the [Botan crypto library](https://github.com/randombit/botan) due to its feature list, maintainer support, availability across all deployment platforms, and ease of use. Also evaluated Crypto++ as a viable candidate, but the additional features of Botan (PKCS#11, TPM, etc) won out.
The random number generator received a backend upgrade. Botan prefers hardware-based RNG's and will provide one if available. This is transparent to KeePassXC and a significant improvement over gcrypt.
Replaced Argon2 library with built-in Botan implementation that supports i, d, and id. This requires Botan 2.11.0 or higher. Also simplified the parameter test across KDF's.
Aligned SymmetricCipher parameters with available modes. All encrypt and decrypt operations are done in-place instead of returning new objects. This allows use of secure vectors in the future with no additional overhead.
Took this opportunity to decouple KeeShare from SSH Agent. Removed leftover code from OpenSSHKey and consolidated the SSH Agent code into the same directory. Removed bcrypt and blowfish inserts since they are provided by Botan.
Additionally simplified KeeShare settings interface by removing raw certificate byte data from the user interface. KeeShare will be further refactored in a future PR.
NOTE: This PR breaks backwards compatibility with KeeShare certificates due to different RSA key storage with Botan. As a result, new "own" certificates will need to be generated and trust re-established.
Removed YKChallengeResponseKeyCLI in favor of just using the original implementation with signal/slots.
Removed TestRandom stub since it was just faking random numbers and not actually using the backend. TestRandomGenerator now uses the actual RNG.
Greatly simplified Secret Service plugin's use of crypto functions with Botan.
Completely rewritten XCB Auto-Type keymap system.
- supports multiple simultaneous layouts
- prefers current layout if it has all keysyms available
- removed hardcoded KeySymMap
- removed clunky custom KeySym emulation
Biggest breaking change is removing KeySym emulation for keys that
do not exist in any of the layouts currently in use. It would be
possible to make it work but if you are trying to type syms that
are not available in any of your layouts you are abusing it. It
also adds unnecessary complexity and opens up timing issues when
the keymap is modified on-the-fly. Now we are just reading it.
This also workarounds a Qt related issue where QX11Info::display()
returns a connection to X server that fails to receive updated
keymap data when client settings change. We use our own connection
now to get it working.
Fixes#5001.
The favicon download URL was constructed from scheme and host only. This is fixed by simply replacing the path of the original URL with "/favicon.ico", thus keeping scheme, host, auth and port intact.
Further modification: URL's with a non-http schema are now rejected.
This change adds a new database settings widget
named "maintenance", using a wrench icon. This widget is designated to be the home for database related maintenance tasks.
Initially, managing custom icons is now possible from that new tab. The feature includes bulk removing of
any number of selected custom icons and automatic purging of unused custom icons by the click of a button.
Fixes#2110
* Closes#4216
Reduced to three-tiered rating system and fixed column implementation. Hide password strength indicator in entry view if excluded from reports.
Introduce password health caching to prevent unnecessary calculations.
