Fix Botan 3 build (#9388)
* 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
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.
Adding debug info to the CLI and the general option
of the main Qt app. Also took time to:
* use `EXIT_SUCCESS`/`EXIT_FAILURE` constants
for main.cpp (this is what is used in `src/cli`);
* fixed `m_initalized` typo;
* added info on debugging mode being disabled
or not;
* regrouped Qt related stuff in the debug output.
Many lines were not conformant with the project's formatting rules.
This patch should fix all formatting and whitespace issues in the code
base.
A clang-format directive was put around the connect() calls containing
SIGNALs and SLOTs whose signatures would be denormalized because of the
formatting rules.
Use nullptr instead of 0 or NULL to initialize a null pointer. In some
cases, readability was enhanced by replacing 0 with more meaningful
values according to the type of the pointer being initialized.
Generation of unit test coverage reports used to be quite complicated
and required a lot of different settings, including a custom CMake
build type. This patch updates the coverage CMake module to only
require -DWITH_COVERAGE=ON to be set on a normal Debug build in order
to create a coverage target.
This patch also moves away from lcov in favor of gcovr, since lcov appears
to be broken in GCC 8. However, the routines for generating lcov reports
still exist, so provided lcov receives updates and there is sufficient
reason to switch back, it is easy to do so.
* Add SHA512 support to CryptoHash
* Add ChaCha20 support
* Add HMAC support
* Add new HmacBlockStream, used in KDBX 4
* Add support for ChaCha20 protected stream
