* Add new top-level algorithm which provides basic functionality: namelloyd2010-11-015-460/+0

* Eliminate the constant size_t values in SymmetricAlgorithm that givelloyd2010-10-282-32/+91
| | | | | | | | | | | | | | | | | | | 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 atlloyd2010-09-071-1/+1
| | | | | | | | | | | | | | 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.
* Update some callers that were using Hex_Encoder or Hex_Decoder butlloyd2010-09-031-13/+6
| | | | | | | | | | | | | | | | | | really didn't need to. The ones in symkey and big_code were actually calling accessor functions to do the encoding themselves without a Pipe (should have definitely recognized that as a code smell). These versions have changed semantically with this checkin - previously they would completely ignore bad inputs, but now invalid inputs are rejected. For instance, you cannot say SymmetricKey key("Only some of this is hex, most of it isn't"); And expect to get a valid key formed by filtering out the non-hex characters and then decoding it. This is almost certainly a good thing. Also fix include in Botan.xs

* 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.

| | | | | | | | | | | | | | | 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).
