* Special thanks to @HexF and @smlu for their contributions towards this feature.
* Add MVP support for Windows Hello as a Quick Unlock solution using the WinRT API. This works by signing a random challenge vector with the Windows Hello protected key store (typically from TPM). The signed challenge is hashed using SHA-256 and then used as the encryption key to encrypt the database credentials. Credentials are encrypted using AES-256/GCM. This ensures the database password can only be decrypted following a successful authentication with Windows Hello in the future.
* Unify Touch ID and Windows Hello behavior under the Quick Unlock branding. Remove all timeout features of Touch ID as they are unnecessary and complicate the feature for no security gain.
* Quick Unlock is automatically reset only when the database key is changed vice whenever database settings are modified.
* Don't set database unlock dialog as always on top. This allows Touch ID and Windows Hello prompts to appear above the dialog properly.
* Prevent quick unlock when using AutoOpen or opening from the command line.
On some systems, although "-fsized-deallocation" compiler flag is there,
compilation will fail because some deallocation functions are missing.
Typically 'operator delete ( void* ptr, std::size_t sz )' is missing on some
macOS systems.
This will check their presence.
On macOS we can have this case when using a compiler that supports the flag,
while the OS doesn't have all the deallocation functions. Typically,
::operator delete(ptr, size) appeared in macOS 10.12
Reported error was:
error: call to unavailable function 'operator delete': introduced in macOS 10.12
* Properly set DEP, ASLR, and Control Flow Guards when building with MSVC
* Improve PDB file (/Zf) creation speed
* Add address sanitization checks in debug builds by default (/fsanitize=address) with MSVC 2019+
* Remove QuaZip dependency in favor of minizip
* Remove signature checks, but maintain signatures for backwards compatibility
* Remove UI components related to certificates except for personal certificate for backwards compatibility
* Default to unsigned containers (*.kdbx)
check_add_gcc_compiler_flag("-fopenmp")
is not robust enough. On some systems and with some compilers
(eg. AppleClang 7) it may say the compiler flag is valid, but later build
fails with:
ld: library not found for -lgomp
Actually, AppleClang doesn't support OpenMP
Replace this check with cmake's FindOpenMP [1] which gives better results.
Output example in case of not found
-- Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)
-- Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES)
-- Could NOT find OpenMP (missing: OpenMP_C_FOUND OpenMP_CXX_FOUND)
Output example in case of found
-- Found OpenMP_C: -fopenmp=libomp (found version "3.1")
-- Found OpenMP_CXX: -fopenmp=libomp (found version "3.1")
-- Found OpenMP: TRUE (found version "3.1")

* 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.

CTest is now run directly and `make coverage` (like `make test`) now
expects you to run `make` beforehand, which is more flexible for the
user. This patch also reduces clutter by properly excluding unwanted
files and reduces the number of explicit exlusion regexes that are
required.
Gcov reports are still confusing and report very low branch coverage
(which is picked up by Codecov, unfortunately), but the llvm-cov reports
are nice and clean now.
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.
Since Homebrew moved all its stuff to /opt/homebrew, our hard-coded
install_name_tool patch magic stopped working. This patch uses
macdeployqt for all executables to prevent this kind of behaviour.
Fixes#6042
The recent macOS security patch renders our codesigning
"fix" of setting the sandbox entitlement to false twice
unusable. This patch adds a full provisioning profile
and adjusts the signing procedure to not include
entitlements for Qt frameworks.
The patch also changes the app and bundle ID, so granted
accessibility privileges have to be granted again after
installing the update.

* Use KeePassXC executable icon for the start menu shortcut on Windows to prevent the icon from being deleted on installation of a new version. Fixes#4226
* Support improvements to windeployqt in Qt 5.14.1+
This causes build failures in Gentoo because we don't allow access to ccache files if ccache is not enabled for build.
Fix this by adding a WITH_CCACHE cmake option and change behavior so that cmake fails if WITH_CCACHE is enabled but ccache program cannot be found.

* Remove deprecation warnings when not doing a DEV_BUILD. Qt 5.14 introduced several deprecation flags on basic function calls in QList and QSet that would require several #pragma ignores. Assuming this was in preparation to Qt 6.0.
* Remove unnecessary assert in PasswordEditWidget that was hit in macOS debug builds.
One some operating systems malloc(3) is not in malloc.h nor in
malloc_np.h, instead it is in stdlib.h.
In addition, not all systems support malloc_usable_size(3). You could
argue it's not safe.
This patch tries to be portable and it fix the build on OpenBSD.
Install with `sudo apt install ccache`.
Makes building a huge lot faster, especially when switching branches.
Nothing happens if ccache is not installed.
Example: (measured on my laptop)
```
$ ccache -C # clear the cache
$ rm -fr build
$ cd build
$ cmake -DWITH_XC_ALL=ON -DCMAKE_BUILD_TYPE=Release ..
$ time make -j4
...

This plugin implements the Secret Storage specification version 0.2.
While running KeePassXC, it acts as a Secret Service server, registered
on DBus, so clients like seahorse, python-secretstorage, or other
implementations can connect and access the exposed database in KeePassXC.

To reduce residual fragments of secret data in memory after
deallocation, this patch replaces the global delete operator with a
version that zeros out previously allocated memory. It makes use of
the new C++14 sized deallocation, but provides an unsized fallback
with platform-specific size deductions.
This change is only a minor mitigation and cannot protect against
buffer reallocations by the operating system or non-C++ libraries.
Thus, we still cannot guarantee all memory to be wiped after free.
As a further improvement, this patch uses libgcrypt and libsodium
to write long-lived master key component hashes into a secure
memory area and wipe it afterwards.
The patch also fixes compiler flags not being set properly on macOS.
* Ensure Qt dlls find plugins in bundled directory
* Reduce complexity of deployment code
* Standardize use of CMAKE_BUILD_TYPE_LOWER for more robust comparisons
Fixes#3023. Fixes part of #1535.
