* For block and stream ciphers, don't set the size of the key vectorslloyd2012-05-252-9/+14
| | | | | | | | | | | until we are actually setting a key. This avoids the problem of prototype objects consuming not just memory but the precious few bytes of mlock'able memory that we're given by Linux. Use clear_mem instead of a loop in BigInt::mask_bits If OS2ECP encounters an invalid format type, include what type it was in the exception message.

* Eliminate the constant size_t values in SymmetricAlgorithm that givelloyd2010-10-281-4/+7
| | | | | | | | | | | | | | | | | | | 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.

* Completely remove the second parameter to SecureVector which specifieslloyd2010-09-141-4/+9
| | | | | | | | | | | | | | | | | | | | the initial/default length of the array, update all users to instead pass the value to the constructor. This is a old vestigal thing from a class (SecureBuffer) that used this compile-time constant in order to store the values in an array. However this was changed way back in 2002 to use the same allocator hooks as the rest of the containers, so the only advantage to using the length field was that the initial length was set and didn't have to be set in the constructor which was midly convenient. However this directly conflicts with the desire to be able to (eventually) use std::vector with a custom allocator, since of course vector doesn't support this. Fortunately almost all of the uses are in classes which have only a single constructor, so there is little to no duplication by instead initializing the size in the constructor.

| | | | | representation (rather than in an interator context), instead use &buf[0], which works for both MemoryRegion and std::vector
* Big, invasive but mostly automated change, with a further attempt atlloyd2010-09-071-5/+5
| | | | | | | | | | | | | | 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.

* Remove SecureBuffer, which is the fixed-size variant of SecureVector.lloyd2010-03-231-3/+3
| | | | | | | | | | | | | | 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
* Un-internal loadstor.h (and its header deps, rotate.h andlloyd2009-12-211-1/+2
| | | | | | | | | | | | | | 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.lloyd2009-12-161-2/+2
| | | | | | | | | | | | | 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 all exception specifications. The way these are designed in C++ islloyd2009-10-222-2/+2

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

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