- update to 2.19.2:
* Add support for parallel computation in Argon2
* Add SSSE3 implementation of Argon2
* The OpenSSL provider was incompatible with OpenSSL 3.0.
It has been removed
* Avoid using reserve in secure_vector appending, which caused
a performance problem
* Fix TLS::Text_Policy behavior when X25519 is disabled
at build time
* Fix several warnings from Clang

OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/Botan?expand=0&rev=111
* Avoid using short exponents when encrypting in ElGamal, as some PGP
implementations generate keys with parameters that are weak when
short exponents are used
* Fix a low risk OAEP decryption side channel
* Work around a miscompilation of SHA-3 caused by a bug in Clang 12
and XCode 13
* Remove support in OpenSSL provider for algorithms which are
disabled by default in OpenSSL 3.0

"DST Root CA X3"
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/Botan?expand=0&rev=108
- Update to 2.16.0:
* Now userspace PRNG objects (such as AutoSeeded_RNG and HMAC_DRBG)
use an internal lock, which allows safe concurrent use. This
however is purely a precaution in case of accidental sharing of
such RNG objects; for performance reasons it is always preferable
to use a RNG per thread if a userspace RNG is needed.
* DL_Group and EC_Group objects now track if they were created
from a known trusted group (such as P-256 or an IPsec DH
parameter). If so, then verification tests can be relaxed, as
compared to parameters which may have been maliciously
constructed in order to pass primality checks.
* RandomNumberGenerator::add_entropy_T assumed its input was a POD
type but did not verify this.
* Support OCSP responders that live on a non-standard port.
* Add support for Solaris sandbox.
* Support suffixes on release numbers for alpha/beta releases.
* Fix a bug in EAX which allowed requesting a 0 length tag, which
had the effect of using a full length tag. Instead omit the
length field, or request the full tag length explicitly.
* Fix a memory leak in GCM where if passed an unsuitable block
cipher (eg not 128 bit) it would throw an exception and leak
the cipher object.

Fix a bug where the name constraint extension did not constrain the alternative
DN field which can be included in a subject alternative name. This would allow
a corrupted sub-CA which was otherwise constrained by a name constraint to
issue a certificate with a prohibited DN.
Fix a bug in the TLS server during client authentication where where if a
(disabled by default) static RSA ciphersuite was selected, then no certificate
request would be sent. This would have an equivalent effect to a client which
simply replied with an empty Certificate message. (GH #2367)
Replace the T-Tables implementation of AES with a 32-bit bitsliced version. As
a result AES is now constant time on all processors. (GH #2346#2348#2353#2329#2355)
In TLS, enforce that the key usage given in the server certificate allows the
operation being performed in the ciphersuite. (GH #2367)
In X.509 certificates, verify that the algorithm parameters are the expected
NULL or empty. (GH #2367)
Change the HMAC key schedule to attempt to reduce the information leaked from
the key schedule with regards to the length of the key, as this is at times (as
for example in PBKDF2) sensitive information. (GH #2362)
Add Processor_RNG which wraps RDRAND or the POWER DARN RNG instructions. The
previous RDRAND_RNG interface is deprecated. (GH #2352)
The documentation claimed that mlocked pages were created with a guard page
both before and after. However only a trailing guard page was used. Add a
leading guard page. (GH #2334)
Add support for generating and verifying DER-encoded ECDSA signatures in the C
and Python interfaces. (GH #2357#2356)
Workaround a bug in GCC’s UbSan which triggered on a code sequence in XMSS (GH
#2322)
When building documentation using Sphinx avoid parallel builds with version 3.0
due to a bug in that version (GH #2326#2324)

- Update to Botan 2.14:
* Add support for using POWER8+ VPSUMD instruction to accelerate GCM (GH #2247)
* Optimize the vector permute AES implementation, especially improving
performance on ARMv7, Aarch64, and POWER. (GH #2243)
* Use a new algorithm for modular inversions which is both faster
and more resistant to side channel attacks. (GH #2287#2296#2301)
* Address an issue in CBC padding which would leak the length of the plaintext
which was being padded. Unpadding during decryption was not affected.
* Optimize NIST prime field reductions, improving ECDSA by 3-9% (GH #2295)

* Add generic CPU target useful when building for some new or unusual platform.
* Disable MD5 in BSI or NIST modes (GH #2188)
* Many currently public headers are being deprecated. If any such header is included by
an application, a warning is issued at compile time.
Headers issuing this warning will be made internal in a future major release.
* RSA signature performance improvements (GH #2068#2070)
* Performance improvements for GCM (GH #2024#2099#2119), OCB (#2122), XTS (#2123) and

* Add support for constant time AES using NEON and AltiVec (GH #2093#2095#2100)
* Improve performance of POWER8 AES instructions (GH #2096)
* Add support for the POWER9 hardware random number generator (GH #2026)
* Add support for 64-bit version of RDRAND, doubling performance on x86-64 (GH #934#2022)
* In DTLS server, support a client crashing and then reconnecting from the same
source port, as described in RFC 6347 sec 4.2.8 (GH #2029)
* Optimize DTLS MTU splitting to split precisely to the set MTU (GH #2042)

* Add support for OCSP stapling on server side. (GH #1703#1967)
* Add a boost::asio TLS stream compatible with boost::asio::ssl. (GH #1839#1927#1992)
* Add a certificate store for Linux/Unix systems. (GH #1885#1936)

- 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.

unblinded Montgomery ladder. As a result, a timing attack can reveal
information about the high bits of the secret key.
* Fix bugs in TLS which caused negotiation failures when the client used an
unknown signature algorithm or version (GH #1711#1709#1708)
* Fix bug affecting GCM, EAX and ChaCha20Poly1305 where if the associated data
was set after starting a message, the new AD was not reflected in the produced
tag. Now with these modes setting an AD after beginning a message throws an
exception.
* Use a smaller sieve which improves performance of prime generation.
* Fixed a bug that caused ChaCha to produce incorrect output after encrypting 256
GB. (GH #1728)
* Add NEON and AltiVec implementations of ChaCha (GH #1719#1728#1729)
* Optimize AVX2 ChaCha (GH #1730)
* Many more operations in BigInt, ECC and RSA code paths are either fully const
time or avoid problematic branches that could potentially be exploited in a
side channel attack. (GH #1738#1750#1754#1755#1757#1758#1759#1762#1765#1770#1773#1774#1779#1780#1794#1795#1796#1797)

* CVE-2018-9860 Fix a bug decrypting TLS CBC ciphertexts which could for a
malformed ciphertext cause the decryptor to read and HMAC an additional 64K

- Update to 1.10.17
- Address a side channel affecting modular exponentiation. An attacker
capable of a local or cross-VM cache analysis attack may be able to recover
bits of secret exponents as used in RSA, DH, etc. CVE-2017-14737 Workaround
a miscompilation bug in GCC 7 on x86-32 affecting GOST-34.11 hash function.
(GH #1192#1148#882, bsc#1060433)
- Add SecureVector::data() function which returns the start of the buffer.
This makes it slightly simpler to support both 1.10 and 2.x APIs in the
same codebase. When compiled by a C++11 (or later) compiler, a template
typedef of SecureVector, secure_vector, is added. In 2.x this class is a
std::vector with a custom allocator, so has a somewhat different interface
than SecureVector in 1.10. But this makes it slightly simpler to support
both 1.10 and 2.x APIs in the same codebase.
- Fix a bug that prevented configure.py from running under Python3
- Botan 1.10.x does not support the OpenSSL 1.1 API. Now the build will
#error if OpenSSL 1.1 is detected. Avoid –with-openssl if compiling against
1.1 or later. (GH #753)
- Import patches from Debian adding basic support for
building on aarch64, ppc64le, or1k, and mipsn32 platforms.
* obsoletes CVE-2017-14737.patch
* refreshes aarch64-support.patch
* drop ppc64le-support.patch for upstream version
(disables altivec support as per concerns by upstream)
- Fix for CVE-2017-14737: A cryptographic cache-based side channel in the RSA
implementation allows local attacker to recover information about RSA secret
keys.

* Fix a bug in X509 DN string comparisons that could result in out of bound
reads. This could result in information leakage, denial of service, or
potentially incorrect certificate validation results. (CVE-2017-2801)
* Avoid use of C++11 std::to_string in some code added in 1.10.14 (GH #747#834)
- Changes from 1.10.15:
* Change an unintended behavior of 2.0.0, which named the include directory
botan-2.0. Since future release of Botan-2 should be compatible with code
written against old versions, there does not seem to be any reason to
* version the include directory with the minor number. (GH #830#833)
* Fix a bug which caused an error when building on Cygwin or other platforms
where shared libraries are not supported. (GH #821)
* Enable use of readdir on Cygwin, which allows the tests to run (GH #824)
* Switch to readthedocs Sphinx theme by default (GH #822#823)

* Fix integer overflow during BER decoding, found by Falko Strenzke.
This bug is not thought to be directly exploitable but upgrading ASAP
is advised. (CVE-2016-9132)
* Fix two cases where (in error situations) an exception would be
thrown from a destructor, causing a call to std::terminate.
* When RC4 is disabled in the build, also prevent it from being
included in the OpenSSL provider. (GH #638)
* Use constant time modular inverse algorithm to avoid possible side
channel attack against ECDSA (CVE-2016-2849)
* Use constant time PKCS #1 unpadding to avoid possible side channel
attack against RSA decryption (CVE-2015-7827)
* Avoid a compilation problem in OpenSSL engine when ECDSA was
disabled. Gentoo bug 542010

- bump SONAME to libbotan-1_10-1
- Update to 1.10.10
* SECURITY: The BER decoder would crash due to reading from offset 0
of an empty vector if it encountered a BIT STRING which did not
contain any data at all. As the type requires a 1 byte field this
is not valid BER but could occur in malformed data. Found with
afl. CVE-2015-5726
* SECURITY: The BER decoder would allocate a fairly arbitrary amount
of memory in a length field, even if there was no chance the read
request would succeed. This might cause the process to run out of
memory or invoke the OOM killer. Found with afl. CVE-2015-5727
* Due to an ABI incompatible (though not API incompatible) change in
this release, the version number of the shared object has been
increased.
* The default TLS policy no longer allows RC4.
* Fix a signed integer overflow in Blue Midnight Wish that may cause
incorrect computations or undefined behavior.
- Update to 1.10.9
* Fixed EAX tag verification to run in constant time
* The default TLS policy now disables SSLv3.
* A crash could occur when reading from a blocking random device if
the device initially indicated that entropy was available but a
concurrent process drained the entropy pool before the read was
initiated.
* Fix decoding indefinite length BER constructs that contain a
context sensitive tag of zero. Github pull 26 from Janusz Chorko.
* The botan-config script previously tried to guess its prefix from
the location of the binary. However this was error prone, and now
the script assumes the final installation prefix matches the value
set during the build. Github issue 29.

- Update to 1.10.8
* Fix a bug in primality testing introduced in 1.8.3 which caused
only a single random base, rather than a sequence of random bases,
to be used in the Miller-Rabin test. This increased the
probability that a non-prime would be accepted, for instance a
1024 bit number would be incorrectly classed as prime with
probability around 2^-40. Reported by Jeff Marrison.
* The key length limit on HMAC has been raised to 512 bytes,
allowing the use of very long passphrases with PBKDF2.
- Update to 1.10.7
* OAEP had two bugs, one of which allowed it to be used even if the
key was too small, and the other of which would cause a crash
during decryption if the EME data was too large for the associated
key.

- Devel package renamed back to Botan-devel to keep rpmlint from
thinking it is a library package ...
- Update to 1.10.0:
New Features:
* SSL (SSLv3, TLS 1.0, and TLS 1.1 are currently supported)
* GOST 34.10-2001 signature scheme (a Russian ECC signature standard
analogous to ECDSA)
* The SHA-3 candidates Keccak and Blue Midnight Wish
* Bcrypt password hashing
* XSalsa20
* AES key wrapping
* Comb4P hash combinator.
Other Changes:
* The block cipher interface now exposes any possible parallelism
available to the implementation, and XTS, CTR, and CBC modes have been
changed to use them.
* SIMD implementations of Serpent, XTEA, Noekeon, and IDEA have been
added, as has an implementation of AES using SSSE3 which runs both in
constant time and, on recent processors, significantly faster than the
usual table based implementation. There have also been numerous
optimizations to elliptic curves.
* The documentation, previously written in LaTeX, is now in
reStructuredText, which is converted into HTML with Sphinx. This new
format is significantly easier to write, encouraging more documentation
to be written and updated. And, indeed, a number of features never
before documented are now described in the manual.
