BSD-2-Clause
* Fri Apr 16 2021 Ferdinand Thiessen <rpm@fthiessen.de>
- Added CVE-2021-24115.patch to fix CVE-2021-24115
* Backport 4db001ca2 to 2.10
* In Botan before 2.17.3, or this backport, constant-time
computations are not used for certain decoding and encoding
operations (base32, base58, base64, and hex)
- Dropped unneeded build requirement gmp,
GNU MP was removed in 1.11.10
* Tue Apr 02 2019 Daniel Molkentin <daniel.molkentin@suse.com>
- 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
removed, since already POSIX and Win32 versions had to be maintained for
portability. (GH #1814)
* Newly generated McEliece and XMSS keys now default to being encrypted using
SIV mode, support for which was added in 2.8.0. Previously GCM was used by
default for these algorithms.
* Use arc4random on Android systems (GH #1851)
* Fix the encoding of PGP-S2K iteration counts (GH #1853 #1854)
* Add a facility for sandboxing the command line util. Currently FreeBSD
(Capsicum) and OpenBSD (pledge) sandboxes are supported. (GH #1808)
* Use if constexpr when available.
* Disable building shared libs on iOS as it was broken and it is not clear
shared libraries are ever useful on iOS (GH #1865)
* Renamed the darwin build target to macos. This should not cause any
user-visible change. (GH #1866)
* Add support for using sccache to cache the Windows CI build (GH #1807)
* Add --extra-cxxflags option which allows adding compilation flags without
overriding the default set. (GH #1826)
* Add --format= option to the hash cli which allows formatting the output as
base64 or base58, default output remains hex.
* Add base58_enc and base58_dec cli utils for base58 encoding/decoding. (GH #1848)
* Enable getentropy by default on macOS (GH #1862)
* Avoid using -momit-leaf-frame-pointer flags, since -fomit-frame-pointer is
already the default with recent versions of GCC.
* Fix XLC sanitizer flags.
* Rename Blake2b class to BLAKE2b to match the official name. There is a typedef for compat.
* Fix a bug where loading a raw Ed25519_PublicKey of incorrect length would
lead to a crash. (GH #1850)
* Fix a bug that caused compilation problems using CryptoNG PRNG. (GH #1832)
* Extended SHAKE-128 cipher to support any key between 1 and 160 bytes,
instead of only multiples of 8 bytes.
* Minor HMAC optimizations.
* Build fixes for GNU/Hurd.
* Fix a bug that prevented generating or verifying Ed25519 signatures in the
CLI (GH #1828 #1829)
* Fix a compilation error when building the amalgamation outside of the
original source directory when AVX2 was enabled. (GH #1812)
* Fix a crash when creating the amalgamation if a header file was edited on
Windows but then the amalgamation was built on Linux (GH #1763)
* Thu Jan 10 2019 Daniel Molkentin <daniel.molkentin@suse.com>
- Update to Botan 2.9
* Bump SONAME
* CVE-2018-20187 Address a side channel during ECC key generation, which used an
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)
* Several optimizations for BigInt and ECC, improving ECDSA performance by as
much as 30%. (GH #1734 #1737 #1777 #1750 #1737 #1788)
* Support recovering an ECDSA public key from a message/signature pair (GH #664
[#1784])
* Add base58 encoding/decoding functions (GH #1783)
* In the command line interface, add support for reading passphrases from the
terminal with echo disabled (GH #1756)
* Add CT::Mask type to simplify const-time programming (GH #1751)
* Add new configure options --disable-bmi2, --disable-rdrand, and
- -disable-rdseed to prevent use of those instruction sets.
* Add error_type and error_code functions to Exception type (GH #1744)
* Now on POSIX systems posix_memalign is used instead of mmap for allocating the
page-locked memory pool. This avoids issues with fork. (GH #602 #1798)
* When available, use RDRAND to generate the additional data in
Stateful_RNG::randomize_with_ts_input
* Use vzeroall/vzeroupper intrinsics to avoid AVX2/SSE transition penalties.
* Support for Visual C++ 2013 has been removed (GH #1557 #1697)
* Resolve a memory leak when verifying ECDSA signatures with versions of OpenSSL
before 1.1.0 (GH #1698)
* Resolve a memory leak using ECDH via OpenSSL (GH #1767)
* Fix an error in XTS which prohibited encrypting values which were exactly the
same length as the underlying block size. Messages of this size are allowed by
the standard and other XTS implementations. (GH #1706)
* Resolve a bug in TSS which resulted in it using an incorrect length field in
the shares. Now the correct length is encoded, but either correct or buggy
lengths are accepted when decoding. (GH #1722)
* Correct a bug when reducing a negative BigInt modulo a small power of 2. (GH
[#1755])
* Add CLI utils for threshold secret splitting. (GH #1722)
* Fix a bug introduced in 2.8.0 that caused compilation failure if using a single
amalgamation file with AVX2 enabled. (GH #1700)
* Add an explicit OS target for Emscripten and improve support for it. (GH #1702)
* Fix small issues when building for QNX
* Switch the Travis CI build to using Ubuntu 16.04 (GH #1767)
* Add options to configure.py to disable generation of pkg-config file, and (for
systems where pkg-config support defaults to off, like Windows), to enable
generating it. (GH #1268)
* Modify configure.py to accept empty lists or trailing/extra commas. (GH #1705)
- Update to Botan 2.8
* Add support for using Apple CommonCrypto library for hashing (GH #1667),
cipher modes (GH #1674) and block ciphers (GH #1673).
* Support for negotiating TLS versions 1.0 and 1.1 is disabled in the default
TLS policy. In addition, support for negotiating TLS ciphersuites using CBC
or CCM mode is disabled by default. Applications which need to interop with
old peers must enable these in their TLS policy object. (GH #1651)
* During primality testing, use a Lucas test in addition to Miller-Rabin. It
is possible to construct a composite integer which passes n Miller-Rabin
tests with probability (1/4)^n. So for a incautious verifier using a small
number of tests (under 16 or so) it is possible if unlikely they would
accept such a composite as prime. Adding a Lucas test precludes such an
attack. (GH #1636)
* Add XChaCha and XChaCha20Poly1305 (GH #1640)
* Add AVX2 implementations of ChaCha (GH #1662) and Serpent (GH #1660)
* Add a new password hashing interface in pwdhash.h (GH #1670)
* C binding improvements. Added functions to get name and supported
keylengths of cipher, hash and MAC objects, support for FE1 format
preserving encryption (GH #1625 #1646), functions to load and save RSA keys
in PKCS #1 format (GH #1621), HOTP and TOTP algorithms, scrypt, certificate
verification (GH #1647), functions to get the output length of public key
operations (GH #1642), and functions for loading and serializing X25519
keys (GH #1681)
* Support for building with BOTAN_MP_WORD_BITS set to 8 or 16 has been removed.
* Previously SM2 had two distinct key types, one for signatures and another
for encryption. They have now been merged into a single key type since in
practice it seems the same key is at times used for both operations. (GH
[#1637])
* The Cipher_Mode class now derives from SymmetricAlgorithm (GH #1639)
* Add support for using the ARMv8 instructions for SM4 encryption (GH #1622)
* The entropy source using SecRandomCopyBytes has been removed as it was
redundant with other entropy sources (GH #1668)
* The Python module has much better error checking and reporting, and offers
new functionality such as scrypt, MPI and FPE. (GH #1643 #1646)
* Fixed a bug that caused CCM to fail with an exception when used with L=8 (GH #1631 #1632)
* The default bcrypt work factor has been increased from 10 to 12.
* The default algorithm used in passhash9 has changed from SHA-256 to
SHA-512, and the default work factor increased from 10 to 15.
* In ECC private keys, include the public key data for compatibility with GnuTLS (GH #1634 #1635)
* Add support for using Linux getrandom syscall to access the system PRNG.
This is disabled by default, use --with-os-feature=getrandom to enable.
* It is now possible to encrypt private keys using SIV mode.
* The FFI function botan_privkey_load now ignores its rng argument.
* Resolve a problem when building under Visual C++ 15.8 (GH #1624)
* Fix a bug in XSalsa20 (192-bit Salsa nonces) where if set_iv was called
twice without calling set_key, the resulting encryption was incorrect. (GH
[#1640])
* Handle an error seen when verifying invalid ECDSA signatures using LibreSSL
on non x86-64 platforms (GH #1627 #1628)
* Fix bugs in PKCS7 and X9.23 CBC padding schemes, which would ignore the
first byte in the event the padding took up the entire block. (GH #1690)
* Correct bugs which would cause CFB, OCB, and GCM modes to crash when they
were used in an unkeyed state. (GH #1639)
* Optimizations for SM4 and Poly1305
* Avoid a cache side channel in the AES key schedule
* Add pk_encrypt and pk_decrypt CLI operations
* Now asn1print CLI defaults to printing context-specific fields.
* Use codec_base for Base64, which matches how Base32 is implemented (GH #1597)
* The cast module has been split up into cast128 and cast256 (GH #1685)
* When building under Visual C++ 2013, the user must acknowledge the upcoming
removal of support using the configure.py flag --ack-vc2013-deprecated (GH
[#1557])
* Tue Jul 31 2018 daniel.molkentin@suse.com
- Fix version in baselibs.conf
* Tue Jul 10 2018 daniel.molkentin@suse.com
- Update to Botan 2.7
* CVE-2018-12435 Avoid a side channel in ECDSA signature generation (GH
[#1604])
* Avoid a side channel in RSA key generation due to use of a non-constant
time gcd algorithm. (GH #1542 #1556)
* Optimize prime generation, especially improving RSA key generation. (GH
[#1542])
* Make Karatsuba multiplication, Montgomery field operations, Barrett
reduction and Montgomery exponentiation const time (GH #1540 #1606 #1609
[#1610])
* Optimizations for elliptic curve operations especially improving reductions
and inversions modulo NIST primes (GH #1534 #1538 #1545 #1546 #1547 #1550)
* Add 24 word wide Comba multiplication, improving 3072-bit RSA and DH by
~25%. (GH #1564)
* Unroll Montgomery reduction for specific sizes (GH #1603)
* Improved performance of signature verification in ECGDSA, ECKCDSA, SM2 and
GOST by 10-15%.
* XMSS optimizations (GH #1583 #1585)
* Fix an error that meant XMSS would only sign half as many signatures as is
allowed (GH #1582)
* Add support for base32 encoding/decoding (GH #1541)
* Add BMI2 optimized version of SHA-256, 40% faster on Skylake (GH #1584)
* Allow the year to be up to 2200 in ASN.1 time objects. Previously this was
limited to 2100. (GH #1536)
* Add support for Scrypt password hashing (GH #1570)
* Add support for using Scrypt for private key encryption (GH #1574)
* Optimizations for DES/3DES, approx 50% faster when used in certain modes
such as CBC decrypt or CTR.
* XMSS signature verification did not check that the signature was of the
expected length which could lead to a crash. (GH #1537)
* The bcrypt variants 2b and 2y are now supported.
* Support for 192-bit Suite B TLS profile is now implemented, as the 128-bit
Suite B is since 2015 not allowed anymore.
* Previously botan allowed GCM to be used with an empty nonce, which is not
allowed by the specification. Now such nonces are rejected.
* Avoid problems on Windows when compiling in Unicode mode (GH #1615 #1616)
* Previously for ASN.1 encoded signatures (eg ECDSA) Botan would accept any
valid BER encoding. Now only the single valid DER encoding is accepted.
* Correct an error that could in rare cases cause an internal error exception
when doing computations with the P-224 curve.
* Optimizations to reduce allocations/copies during DER encoding and BER
decoding (GH #1571 #1572 #1600)
* Botan generates X.509 subject key IDs by hashing the public key with
whatever hash function is being used to sign the certificate. However
especially for SHA-512 this caused SKIDs that were far longer than
necessary. Now all SKIDs are truncated to 192 bits.
* In the test suite use mkstemp to create temporary files instead of creating
them in the current working directory. (GH #1533 #1530)
* It is now possible to safely override CXX when invoking make in addition to
when configure.py is run. (GH #1579)
* OIDs for Camellia and SM4 in CBC and GCM mode are now defined, making it
possible to use this algorithms for private key encryption.
* Avoid creating symlinks to the shared object on OpenBSD (#1535)
* The factor command runs much faster on larger inputs now.
* Support for Windows Phone/UWP was deprecated starting in 2.5. This
deprecation has been reversed as it seems UWP is still actively used. (GH
[#1586] #1587)
* Support for Visual C++ 2013 is deprecated, and will be removed in Jan 2019.
* Added support for GCC’s –sysroot option to configure.py for
cross-compiling.
* Thu Apr 12 2018 kasimir_@outlook.de
- fixed to build on armv6 and armv7
* Tue Apr 10 2018 daniel.molkentin@suse.com
- Update to Botan 2.6
* 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
bytes of data which is not part of the record. This could cause a crash if
the read went into unmapped memory. No information leak or out of bounds
write occurs.
* Add support for OAEP labels (GH #1508)
* RSA signing is about 15% faster (GH #1523) and RSA verification is about 50% faster.
* Add exponent blinding to RSA (GH #1523)
* Add Cipher_Mode::create and AEAD_Mode::create (GH #1527)
* Fix bug in TLS server introduced in 2.5 which caused connection to fail if
the client offered any signature algorithm not known to the server (for
example RSA/SHA-224).
* Fix a bug in inline asm that would with GCC 7.3 cause incorrect
computations and an infinite loop during the tests. (GH #1524 #1529)
* Tue Apr 03 2018 daniel.molkentin@suse.com
- Update to Botan 2.5
* Fix error in certificate wildcard matching (CVE-2018-9127), where a
wildcard cert for b*.example.com would be accepted as a match for any host
with name *b*.example.com (GH #1519)
* Add support for RSA-PSS signatures in TLS (GH #1285)
* Ed25519 certificates are now supported (GH #1501)
* Many optimizations in ECC operations. ECDSA signatures are 8-10 times
faster. ECDSA verification is about twice as fast. ECDH key agreement is
3-4 times faster. (GH #1457 #1478)
* Implement product scanning Montgomery reduction, which improves
Diffie-Hellman and RSA performance by 10 to 20% on most platforms. (GH
[#1472])
* DSA signing and verification performance has improved by 30-50%.
* Add a new Credentials_Manager callback that specifies which CAs the server
has indicated it trusts (GH #1395 fixing #1261)
* Add new TLS::Callbacks methods that allow creating or removing extensions,
as well as examining extensions sent by the peer (GH #1394 #1186)
* Add new TLS::Callbacks methods that allow an application to negotiate use
of custom elliptic curves. (GH #1448)
* Add ability to create custom elliptic curves (GH #1441 #1444)
* Add support for POWER8 AES instructions (GH #1459 #1393 #1206)
* Fix DSA/ECDSA handling of hashes longer than the group order (GH #1502
[#986])
* The default encoding of ECC public keys has changed from compressed to
uncompressed point representation. This improves compatability with some
common software packages including Golang’s standard library. (GH #1480
[#1483])
* It is now possible to create DNs with custom components. (GH #1490 #1492)
* It is now possible to specify the serial number of created certificates,
instead of using the default 128-bit random integer. (GH #1489 #1491)
* Change DL_Group and EC_Group to store their data as shared_ptr for fast
copying. Also both classes precompute additional useful values (eg for
modular reductions). (GH #1435 #1454)
* Make it possible for PKCS10 requests to include custom extensions. This
also makes it possible to use muliple SubjectAlternativeNames of a single
type in a request, which was previously not possible. (GH #1429 #1428)
* Add new optimized interface for FE1 format preserving encryption. By
caching a number of values computed in the course of the FPE calculation,
it provides a 6-7x speedup versus the old API. (GH #1469)
* Add DSA and ElGamal keygen functions to FFI (#1426)
* Add Pipe::prepend_filter to replace Pipe::prepend (GH #1402)
* Fix a memory leak in the OpenSSL block cipher integration, introduced in
* 2.2.0
* Use an improved algorithm for generating safe primes which is several tens
of times faster. Also, fix a bug in the prime sieving algorithm which
caused standard prime generation (like for RSA keys) to be slower than
necessary. (GH #1413 #1411)
* Correct the return value of PK_Encryptor::maximum_input_size which reported
a much too small value (GH #1410)
* Remove use of CPU specific optimization flags, instead the user should set
these via CXXFLAGS if desired. (GH #1392)
* Resolve an issue that would cause a crash in the tests if they were run on
a machine without SSE2/NEON/VMX instructions. (GH #1495)
* The Python module now tries to load DLLs from a list of names and uses the
first one which successfully loads and indicates it supports the desired
API level. (GH #1497)
* Various minor optimizations for SHA-3 (GH #1433 #1434)
* The output of botan --help has been improved (GH #1387)
* Add --der-format flag to command line utils, making it possible verify
DSA/ECDSA signatures generated by OpenSSL command line (GH #1409)
* Add support for --library-suffix option to configure.py (GH #1405 #1404)
* Use feature flags to enable/disable system specific code (GH #1378)
* Add --msvc-runtime option to allow using static runtime (GH #1499 #210)
* Add –enable-sanitizers= option to allow specifying which sanitizers to
enable. The existing --with-sanitizers option just enables some default set
which is known to work with the minimum required compiler versions.
* Use either rst2man or rst2man.py for generating man page as distributions
differ on where this program is installed (GH #1516)
* The threefish module has been renamed threefish_512 since that is the
algorithm it provides. (GH #1477)
* The Perl XS based wrapper has been removed, as it was unmaintained and
broken. (GH #1412)
* The sqlite3 encryption patch under contrib has been removed. It is still
maintained by the original author at
https://github.com/OlivierJG/botansqlite3

Changes and new features:
* Several build improvements requested by downstream packagers,
including the ability to disable building the static library. All
makefile constructs that were specific to nmake or GNU make have
been eliminated, thus the option ``--makefile-style`` which was
previously used to select the makefile type has also been
removed. (GH #1230 #1237 #1300 #1318 #1319 #1324 #1325 #1346)
* Support for negotiating the DH group as specified in RFC 7919 is
now available in TLS (GH #1263)
* Support for ARIA-GCM ciphersuites are now available in TLS. They
are disabled by default. (GH #1284)
* Add support for generating and verifying X.509 objects
(certificates, CRLs, etc) using RSA-PSS signatures (GH #1270 and
[#1368])
* Add support for AES key wrapping with padding, as specified in RFC
5649 and NIST SP 800-38F (GH #1301)
* OCSP requests made during certificate verification had the
potential to hang forever. Now the sockets are non-blocking and a
timeout is enforced. (GH #1360 fixing GH #1326)
* Add ``Public_Key::fingerprint_public`` which allows fingerprinting
the public key.
The previously available ``Private_Key::fingerprint`` is
deprecated, now ``Private_Key::fingerprint_private`` should be
used if this is required. (GH #1357)
* ECC certificates generated by Botan used an invalid encoding for
the parameters field, which was rejected by some certificate
validation libraries notably BouncyCastle. (GH #1367)
* Loading an ECC key which used OID encoding for the domain
parameters, then saving it, would result in a key using the
explicit parameters encoding. Now the OID encoding is
retained. (GH #1365)
* Correct various problems in certificate path validation that arose
when multiple paths could be constructed leading to a trusted root
but due to other constraints only some of them validated. (GH
[#1363])
* It is now possible for certificate validation to return warning
indicators, such as that the distinguished name is not within
allowed limits or that a certificate with a negative serial number
was observed. (GH #1363 #1359)
* XMSS signatures now are multi-threaded for improved performance
(GH #1267)
* Fix a bug that caused the TLS peer cert list to be empty on a
resumed session. (GH #1303 #1342)
* Increase the maximum HMAC key length from 512 bytes to 4096
bytes. This allows using a DH key exchange in TLS with a group
greater than 4096 bits. (GH #1316)
* Fix a bug in the TLS server where, on receiving an SSLv3 client
hello, it would attempt to negotiate TLS v1.2. Now a
protocol_version alert is sent. Found with tlsfuzzer. (GH #1316)
* Fix several bugs related to sending the wrong TLS alert type in
various error scenarios, caught with tlsfuzzer.
* Add support for a ``tls_http_server`` command line utility which
responds to simple GET requests. This is useful for testing
against a browser, or various TLS test tools which expect the
underlying protocol to be HTTP. (GH #1315)
* Add an interface for generic PSK data stores, as well as an
implementation which encrypts stored values with AES key
wrapping. (GH #1302)
* Optimize GCM mode on systems both with and without carryless
multiply support. This includes a new base case implementation
(still constant time), a new SSSE3 implementation for systems with
SSSE3 but not clmul, and better algorithms for systems with clmul
and pmull. (GH #1253 #1263)
* Various optimizations for OCB, CFB, CTR, SM3, SM4, GMAC, BLAKE2b,
Blowfish, Twofish, CAST-128, and CRC24 (GH #1281)
* Salsa20 now supports the seek operation.
* Add ``EC_Group::known_named_groups`` (GH #1339)
* Symmetric algorithms (block ciphers, stream ciphers, MACs) now
verify that a key was set before accepting data. Previously
attempting to use an unkeyed object would instead result in either
a crash or invalid outputs. (GH #1279)
* The X509 certificate, CRL and PKCS10 types have been heavily
refactored internally. Previously all data of these types was
serialized to strings, then in the event a more complicated data
structure (such as X509_DN) was needed, it would be recreated from
the string representation. However the round trip process was not
perfect and could cause fields to become lost. This approach is no
longer used, fixing several bugs (GH #1010 #1089 #1242 #1252). The
internal data is now stored in a ``shared_ptr``, so copying such
objects is now very cheap. (GH #884)
* ASN.1 string objects previously held their contents as ISO 8859-1
codepoints. However this led to certificates which contained
strings outside of this character set (eg in Cyrillic, Greek, or
Chinese) being rejected. Now the strings are always converted to
UTF-8, which allows representing any character. In addition, UCS-4
strings are now supported. (GH #1113 #1250 #1287 #1289)
* It is now possible to create an uninitialized X509_Certificate
object. Such an object will throw if any attempt to access its
members is made. (GH #1335)
* In BER decoder, avoid unbounded stack recursion when parsing
nested indefinite length values. Now at most 16 nested indefinite
length values are accepted, anything deeper resulting in a
decoding error. (GH #1304 OSS-Fuzz 4353).
* A new ASN.1 printer API allows generating a string representation
of arbitrary BER data. This is used in the ``asn1print`` command
line utility and may be useful in other applications, for instance
for debugging.
* New functions for bit rotations that distinguish rotating by a
compile-time constant vs a runtime variable rotation. This allows
better optimizations in both cases. Notably performance of
CAST-128 and CAST-256 are substantially improved. (GH #1247)
* TLS CBC ciphersuites now are implemented using the standard CBC
code, instead of reimplementing CBC inside the TLS stack. This
allows for parallel decryption of TLS CBC ciphertexts, and
improves performance especially when using AES hardware
support. (GH #1269)
* Add callbacks to make it possible for an application using TLS to
provide custom implementations of signature schemes, eg when
offloading the computations to another device. (GH #1332)
* Use a direct calculation for calendar computations instead of
relying on non-portable operating system interfaces. (GH #1336)
* Fix a bug in the amalgamation generation which could cause build
failures on some systems including macOS. (GH #1264 #1265)
* A particular code sequence in TLS handshake would always (with an
ECC ciphersuite) result in an exception being thrown and then
caught. This has changed so no exception is thrown. (GH #1275)
* The code for byteswapping has been improved for ARMv7 and for
Windows x86-64 systems using MSVC. (GH #1274)
* The GMAC class no longer derives from GHASH. This should not cause
any noticeable change for applications. (GH #1253)
* The base implementation of AES now uses a single 4K table, instead
of 4 such tables. This offers a significant improvement against
cache-based side channels without hurting performance too much. In
addition the table is now guaranteed to be aligned on a cache
line, which ensures the additional countermeasure of reading each
cache line works as expected. (GH #1255)
* In TLS client resumption, avoid sending a OCSP stapling
request. This caused resumption failures with some servers. (GH
[#1276])
* The overhead of making a call through the FFI layer has been
reduced.
* The IDs for SHA-3 PKCSv1.5 signatures added in 2.3.0 were
incorrect. They have been changed to use the correct encoding, and
a test added to ensure such errors do not recur.
* Counter mode allows setting a configurable width of the
counter. Previously it was allowed for a counter of even 8 bits
wide, which would mean the keystream would repeat after just 256
blocks. Now it requires the width be at least 32 bits. The only
way this feature could be used was by manually constructing a
``CTR_BE`` object and setting the second parameter to something in
the range of 1 to 3.
* A new mechanism for formatting ASN.1 data is included in
``asn1_print.h``. This is the same functionality used by the
command line ``asn1print`` util, now cleaned up and moved to the
library.
* Add ``Pipe::append_filter``. This is like the existing
(deprecated) ``Pipe::append``, the difference being that
``append_filter`` only allows modification before the first call
to ``start_msg``. (GH #1306 #1307)
* The size of ASN1_Tag is increased to 32 bits. This avoids a
problem with UbSan (GH #751)
* Fix a bug affecting bzip2 compression. In certain circumstances,
compression would fail with ``BZ_SEQUENCE_ERROR`` due to calling
bzlib in an way it does not support. (GH #1308 #1309)
* In 2.3.0, final annotations were added to many classes including
the TLS policies (like ``Strict_Policy`` and
``BSI_TR_02102_2``). However it is reasonable and useful for an
application to derive from one of these policies, so as to create
an application specific policy that is based on a library-provided
policy, but with a few tweaks. So the final annotations have been
removed on these classes. (GH #1292)
* A new option ``--with-pdf`` enables building a PDF copy of the
handbook. (GH #1337)
* A new option ``--with-rst2man`` enables building a man page for
the command line util using Docutils rst2man. (GH #1349)
* Support for NEON is now enabled under Clang.
* Now the compiler version is detected using the preprocessor,
instead of trying to parse the output of the compiler's version
string, which was subject to problems with localization. (GH
[#1358])
* By default the gzip compressor will not include a timestamp in the
header. The timestamp can be set by passing it to the
``Gzip_Compression`` constructor.
* Add an OID for RIPEMD-160
* Fixes for CMake build (GH #1251)
* Avoid some signed overflow warnings (GH #1220 #1245)
* As upstream support for Native Client has been deprecated by
Google, support is now also deprecated in Botan and will be
removed in a future release.
* The Perl-XS wrapper has not been maintained in many years. It is
now deprecated, and if no attempts are made to revive it, it will
be removed in a future release.
* Support for building on IRIX has been removed.
* Thu Jan 11 2018 i@marguerite.su

- 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.

- Update to 1.10.16 (Fixes CVE-2017-2801, bsc#1033605)
* 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)
* Wed Dec 28 2016 pth@suse.de
- Update to 1.10.14
* 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)
* Sun Nov 13 2016 netsroth@opensuse.org
- Update to 1.10.13
* Use constant time modular inverse algorithm to avoid possible side

- Update to 1.10.12
- Version 1.10.12, 2016-02-03
* In 1.10.11, the check in PointGFp intended to check the affine y
argument actually checked the affine x again. Reported by Remi Gacogne
* The CVE-2016-2195 overflow is not exploitable in 1.10.11 due to an
additional check in the multiplication function itself which was also
added in that release, so there are no security implications from the
missed check. However to avoid confusion the change was pushed in a new
release immediately.
* The 1.10.11 release notes incorrectly identified CVE-2016-2195 as
CVE-2016-2915
- Version 1.10.11, 2016-02-01
* Resolve heap overflow in ECC point decoding. CVE-2016-2195

- Fix Source0 URL
* Tue Aug 11 2015 netsroth@opensuse.org
- 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.
