* MD4's M buffer was set to be 48 words instead of 16. This had beenlloyd2010-02-031-1/+1
| | | | | | | | | | | | | | extant for a long long time and was never caught because until recently the code did not depend on M.size(). However with the recent loadstore changes that use memcpy to load the entire array in one shot, an extra 128 bytes of memory would be read (but not used) in each iteration. This probably did not cause any problems except for Valgrind warnings, though in some situations it would be possible for the M buffer and MDx_HashFunctions buffer to be close enough that memcpy would be called with overlapping regions, which could cause arbitrarily weird failures since memcpy is allowed to assume they do not overlap.

* Un-internal loadstor.h (and its header deps, rotate.h andlloyd2009-12-2119-30/+31
| | | | | | | | | | | | | | bswap.h); too many external apps rely on loadstor.h existing. Define 64-bit generic bswap in terms of 32-bit bswap, since it's not much slower if 32-bit is also generic, and much faster if it's not. This may be quite helpful on 32-bit x86 in particular. Change formulation of generic 32-bit bswap. It may be faster or slower depending on the CPU, especially the latency and throuput of rotate instructions, but should be faster on an ideally superscalar processor with rotate instructions (ie, what I expect future CPUs to look more like).
* Add missing BOTAN_DLL exports.lloyd2009-12-161-1/+1
| | | | Move most of the engine headers to internal
* Make many more headers internal-only.lloyd2009-12-1620-32/+32
| | | | | | | | | | | | | Fixes for the amalgamation generator for internal headers. Remove BOTAN_DLL exporting macros from all internal-only headers; the classes/functions there don't need to be exported, and avoiding the PIC/GOT indirection can be a big win. Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc For GCC, use -fvisibility=hidden and set BOTAN_DLL to the visibility __attribute__ to export those classes/functions.

| | | | | | | | | | | | on a particular ISA extension rather than a list of CPUs. Much easier to edit and audit, too. Add markers on the AES-NI code and SHA-1/SSE2. Serpent and XTEA don't need it because they are generic and only depend on simd_32 which will silenty swap out a scalar version if SSE2/AltiVec isn't enabled (since it turns out on supersclar processors just doing 4 blocks in parallel can be a win even in GPRs). Add pentium3 to the list of CPUs with rdtsc, was missing. Odd!

| * Conver the rest of the hash functions to use the array-based load instructions.lloyd2009-11-035-40/+41
| | | | | | | | | | | | | | I'm not totally happy with this - in particular in all cases the size is a compile time constant - it would be nice to make use of this via tempalate metaprogramming. Also for matching endian loads, a straight memcpy would do the work, which would probably be even faster.

| | | | | | | | | | | | | | | | change some of the hash functions to use it as low hanging fruit. Probably could use further optimization (just unrolls x4 currently), but merely having it as syntax is good as it allows optimizing many functions at once (eg using SSE2 to do 4-way byteswaps).

| | | | | | | | | | | | and all CPU-specific implementations now depend on the appropriate engine module. The most common problem before with this was that the SSE2 module was built, but the sole SSE2 code (SHA-1) was not (for instance, on an i686). This would cause a compile warning about the unused request object. Preventing unused engines from being built will also (very slightly) speed up the lookup process on most system.

| | | | | | | | | | | | | | Add a comment that the limitation of the personalization string being a maximum of 64 characters is due to the implementation and not the specification (but it makes it easy to implement, and in this particular case 64 characters is probably fine). Add some tests for the personalization option, generated by the Skein reference implementation. Disable stripping whitespace in checks/misc.cpp:strip - it strips the personalization tag, which breaks the test, and isn't needed otherwise because the test files are well-formed.
