* Add deleted copy constructors/assignment operators where appropriate.lloyd2012-07-101-0/+4
| | | | | Replace C++98 style private copy constructors/assignment ops with ones annotated with delete.

* Fairly huge update that replaces the old secmem types with std::vectorlloyd2012-05-181-1/+1
| | | | | | using a custom allocator. Currently our allocator just does new/delete with a memset before deletion, and the mmap and mlock allocators have been removed.
* First step towards replacing the existing containers with std::vectorlloyd2012-05-181-2/+2
| | | | | | with a custom allocator; remove the 3 argument version of MemoryRegion::copy, replacing with freestanding buffer_insert function.
* PR 145 was based around an easy misunderstanding of the CTR code.lloyd2011-04-051-10/+16
| | | | | | Add some comments to help explain what is going on. Also add a test using 512 blocks; all the existing ones were shorter, so increment was not being tested at all. :(

| | | | | | | | | | | | | | | | | | | the parameters of the key length. Instead define a new function which returns a simple object which contains this information. This definitely breaks backwards compatability, though only with code that directly manipulates low level objects like BlockCipher*s directly, which is probably relatively rare. Also remove some deprecated accessor functions from lookup.h. It turns out block_size_of and output_size_of are being used in the TLS code; I need to remove them from there before I can delete these entirely. Really that didn't make much sense, because they assumed all implementations of a particular algorithm will have the same specifications, which is definitely not necessarily true, especially WRT key length. It is much safer (and probably simpler) to first retrieve an instance of the actual object you are going to use and then ask it directly.

* Big, invasive but mostly automated change, with a further attempt atlloyd2010-09-071-3/+3
| | | | | | | | | | | | | | harmonising MemoryRegion with std::vector: The MemoryRegion::clear() function would zeroise the buffer, but keep the memory allocated and the size unchanged. This is very different from STL's clear(), which is basically the equivalent to what is called destroy() in MemoryRegion. So to be able to replace MemoryRegion with a std::vector, we have to rename destroy() to clear() and we have to expose the current functionality of clear() in some other way, since vector doesn't support this operation. Do so by adding a global function named zeroise() which takes a MemoryRegion which is zeroed. Remove clear() to ensure all callers are updated.

* 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.
* 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.
* Make many more headers internal-only.lloyd2009-12-161-1/+1
| | | | | | | | | | | | | 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.
