1.9.3: Adding AES-NI and format preserving encryption
Botan 1.9.3 was released this evening.A new engine, aes_isa_eng, adds hooks for CPU-specific
implementations of AES. Currently supported is an implementation for
Intel's AES-NI; while no currently shipping CPU has support for AES-NI
yet, the code was tested using Intel's SDE.
The engine may be extended in the future to support VIA's PadLock
instructions or other similar extensions.
An implementation of format-preserving encryption (FPE) was added. FPE allows for encrypting data in such a way that format constraints are retained. An example which uses this to encrypt credit card numbers with valid Luhn checksums to other credit card numbers with valid checksums is available.
An interface change in how X.509 certificates and PKCS #10 certificate requests are created now allows for using arbitrary hash functions; previously the use of SHA-1 was hardcoded, which is particularly undesirable given the currently known attacks on that algorithm.
The implementations of MARS, Skipjack, and AES were optimized to varying degrees.
The previous release added support for AltiVec but it was not
enabled unless a macro was set by hand. Now it is set by default if
the build is configured for a G4, G5, POWER6 or POWER7 processor (all
of which include AltiVec in all known configurations). A similar
mechanism sets macros indicating support for SSE2 and SSSE3 (though
SSSE3 is not currently used in the codebase), and for AES-NI. Support
for a particular ISA extension can also be enabled at build time by
using the new --with-isa-extension option to
configure.py.
The default build for Windows is now a DLL, mostly due to the much smaller size of the resulting binary. This is particularly important because this release also adds support for packaging botan using the InnoSetup Windows installer program. This should definitely be considered experimental, but seems to work. You can download an installer for 1.9.3 right now. Comments on the quality of the Windows installer or ways it could be improved would be heartily welcomed.

< Botan 1.8.8 and 1.9.2 | 1.9.4 adds SSL/TLS, GOST 34.10, XSalsa20, fault countermeasures, SIMD optimizations >
I'm trying the experimental setup you put together with VC 2008 Express. When I try to compile it finds the includes correctly, but the linking fails with a strange "6 unresolved externals" for the LibraryInitializer. I've double-checked my library path.
Since I'm presently waiting for approval on the mailing list, what do you suggest that I do?
Please provide compiled with mingw binaries! i am having trouble compiling Botan with MinGW on Windows XP!

Dipish,
The GCC included with MinGW is quite ancient, I believe, and does not include TR1. You'll want to pass --with-tr1=none to configure.py to get a build.
How can I Change the default build for Windows to static lib?
Goldenscale,
Normally that is handled with --disable-shared, which will cause VC to generate only a static import lib. However this behavior is broken in 1.9.3.
