* Use "/*" instead of "/**" in starting comments at the begining of a file.lloyd2010-06-071-1/+1
| | | | | This caused Doxygen to think this was markup meant for it, which really caused some clutter in the namespace page.
* Change BlockCipher::parallelism() to return the native parallelism oflloyd2010-05-251-1/+1
| | | | | | | | | | | | | | | | | | | | the implementation rather than the preferred one. Update all implementations. Add a new function parallel_bytes() which returns parallelism() * BLOCK_SIZE * BUILD_TIME_CONSTANT This is because i noticed all current calls of parallelism() just multiplied the result by the block size already, so this simplified that code. The build time constant is set to 4, which was the previous default return value of parallelism(). However the SIMD versions returned 2*native paralellism rather than 4*, so this increases the buffer sizes used for those algorithms. The constant multiple lives in buildh.in and build.h, and is named BOTAN_BLOCK_CIPHER_PAR_MULT.
* Remove SecureBuffer, which is the fixed-size variant of SecureVector.lloyd2010-03-234-11/+11
| | | | | | | | | | | | | | 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

* Instead of the mode parallelism being specified via macros, have itlloyd2010-02-251-2/+2
| | | | | | | | | depend on the particular implementation. Add a new virtual function to BlockCipher named parallelism that returns the number of blocks the cipher object could or might want to process in parallel. Currently set to 1 by default but may make sense to increase this for even scalar implementations since it seems like better caching behavior makes it a win.
* Clean up exceptions. Remove some unused ones like Config_Error. Makelloyd2010-01-051-2/+2
| | | | | | | Invalid_Argument just a typedef for std::invalid_argument. Make Botan::Exception a typedef for std::runtime_error. Make Memory_Exhaustion a public exception, and use it in other places where memory allocations can fail.
* Un-internal loadstor.h (and its header deps, rotate.h andlloyd2009-12-213-3/+5
| | | | | | | | | | | | | | 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).
* Make many more headers internal-only.lloyd2009-12-166-9/+9
| | | | | | | | | | | | | 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.

* Remove the 'realname' attribute on all modules and cc/cpu/os info files.lloyd2009-10-297-15/+0
| | | | | Pretty much useless and unused, except for listing the module names in build.h and the short versions totally suffice for that.
* Remove all exception specifications. The way these are designed in C++ islloyd2009-10-2213-13/+13
| | | | | | just too fragile and not that useful. Something like Java's checked exceptions might be nice, but simply killing the process entirely if an unexpected exception is thrown is not exactly useful for something trying to be robust.

| | | | | | | | | | | | | Remove encrypt, decrypt - replace by cipher() and cipher1() Remove seek() - not well supported/tested, I want to redo with a new interface once CTR and OFB modes become stream ciphers. Rename resync to set_iv() Remove StreamCipher::IV_LENGTH and add StreamCipher::valid_iv_length() to allow multiple IV lengths (as for instance Turing allows, as would Salsa20 if XSalsa20 were supported).

* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-3011-135/+157
| | | | | | | | | | | | | | | up during the Fedora submission review, that each source file include some text about the license. One handy Perl script later and each file now has the line Distributed under the terms of the Botan license after the copyright notices. While I was in there modifying every file anyway, I also stripped out the remainder of the block comments (lots of astericks before and after the text); this is stylistic thing I picked up when I was first learning C++ but in retrospect it is not a good style as the structure makes it harder to modify comments (with the result that comments become fewer, shorter and are less likely to be updated, which are not good things).
