- Update to Botan 2.10
* Bump SONAME
* Warning: XMSS currently implements draft-06 which is not compatible with
the final RFC 8391 specification. A PR is open to fix this, however it will
break all current uses of XMSS. If you are currently using XMSS please
comment at https://github.com/randombit/botan/pull/1858. Otherwise the PR
will be merged and support for draft-06 will be removed starting in 2.11.
* Added a new certificate store implementation that can access the MacOS
keychain certificate store. (GH #1830)
* Redesigned Memory_Pool class, which services allocations out of a set of
pages locked into memory (using mlock/VirtualLock). It is now faster and
with improved exploit mitigations. (GH #1800)
* Add BMI2 implementations of SHA-512 and SHA-3 which improve performance by
25-35% on common CPUs. (GH #1815)
* Unroll SHA-3 computation improving performance by 10-12% (GH #1838)
* Add a Thread_Pool class. It is now possible to run the tests in multiple
threads with --test-threads=N flag to select the number of threads to use.
Use --test-threads=0 to run with as many CPU cores as are available on the
current system. The default remains single threaded. (GH #1819)
* XMSS signatures now uses a global thread pool instead of spawning new
threads for each usage. This improves signature generation performance by
between 10% and 60% depending on architecture and core count. (GH #1864)
* Some functions related to encoding and decoding BigInts have been
deprecated. (GH #1817)
* Binary encoding and decoding of BigInts has been optimized by performing
word-size operations when possible. (GH #1817)
* Rename the exception Integrity_Failure to Invalid_Authentication_Tag to
make its meaning and usage more clear. The old name remains as a typedef.
(GH #1816)
* Support for using Boost filesystem and MSVC’s std::filesystem have been
