* Use "/*" instead of "/**" in starting comments at the begining of a file.lloyd2010-06-079-9/+9
| | | | | This caused Doxygen to think this was markup meant for it, which really caused some clutter in the namespace page.

* Check to make sure the user didn't provide two of the same has forlloyd2010-04-231-0/+3
| | | | | | Comb4P. If you do this, the first N bytes are all zero, which could expose some problems, especially if the caller truncates or is relying on Comb4P acting like a random function.

* Remove SecureBuffer, which is the fixed-size variant of SecureVector.lloyd2010-03-2317-33/+33
| | | | | | | | | | | | | | Add a second template param to SecureVector which specifies the initial length. Change all callers to be SecureVector instead of SecureBuffer. This can go away in C++0x, once compilers implement N2712 ("Non-static data member initializers"), and we can just write code as SecureVector<byte> P{18}; instead

* 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.
* Move the get_byte template to its own header, because many fileslloyd2010-02-023-3/+0

* Use a u32bit for the length argument to ubi_512. That value cannot possiblylloyd2009-12-231-2/+2
| | | | | | be larger than 4294967232 because you can give at most 2^32-1 bytes of data at a time to Skein_512::add_data, and Skein always needs to buffer at least one byte.
* 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.

* Add a new need_isa marker for info.txt that lets a module dependlloyd2009-11-061-13/+2
| | | | | | | | | | | | 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.
| * Add a new looping load_be / load_le for loading large arrays at once, andlloyd2009-10-2910-49/+58
| | | | | | | | | | | | | | | | 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).
