- 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)
