Version 1.11.16, 2015-03-29
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* TLS has changed from using the non-standard NPN extension to the IETF
standardized ALPN extension for negotiating an application-level protocol.
Unfortunately the semantics of the exchange have changed with ALPN. Using
NPN, the server offered a list of protocols it advertised, and then the
client chose its favorite. With ALPN, the client offers a list of protocols
and the server chooses. The the signatures of both the TLS::Client and
TLS::Server constructors have changed to support this new flow.
* Optimized ECDSA signature verification thanks to an observation by
Dr. Falko Strenzke. On some systems verifications are between 1.5
and 2 times faster than in 1.11.15.
* RSA encrypt and decrypt operations using OpenSSL have been added.
* Public key operation types now handle all aspects of the operation,
such as hashing and padding for signatures. This change allows
supporting specialized implementations which only support particular
padding types.
* Added global timeout to HMAC_RNG entropy reseed. The defaults are
the values set in the build.h macros `BOTAN_RNG_AUTO_RESEED_TIMEOUT`
and `BOTAN_RNG_RESEED_DEFAULT_TIMEOUT`, but can be overriden
on a specific poll with the new API call reseed_with_timeout.
* Fixed Python cipher update_granularity() and default_nonce_length()
functions
* The library now builds on Visual C++ 2013
* The GCM update granularity was reduced from 4096 to 16 bytes.
* Fix a bug that prevented building the amalgamation until a non-amalgamation
configuration was performed first in the same directory.
* Add Travis CI integration. Github pull 60.
