* Realization while thinking about the recently added truncate: in a STLlloyd2010-09-071-1/+1
| | | | | | | | | | | | | | | | | | container like vector, truncate is simply resize, but what MemoryRegion called resize will zap the entire contents, and then what was resize was called grow_to. This is really problematic in terms of the goal of replacing MemoryRegion with a vector with a custom allocator. In this checkin: - Remove MemoryRegion::grow_to and MemoryRegion::truncate - Change the semantics of MemoryRegion::resize to change the size while keeping any current contents intact (up to the new size), zero initializing any new values. Unrelated, just noticed the lack while I was in there, add a version of CryptoBox::decrypt taking a std::string for the input.
* Add a standalone version of hex encoding and decoding, defining the filterslloyd2010-09-033-0/+289
| | | | | | | | in terms of these calls. The header for the hex filter is renamed hex_filt.h. This probably won't affect people because filters.h (included by botan.h) already included hex.h, and now just includes hex_filt.h instead.
* Move most code that relies heavily on Filters into src/filters.lloyd2009-11-174-344/+0
| | | | | | Remove support for (unused) modset settings. Move tss, fpe, cryptobox, and aont to new dir constructs
* Rename/remove some secmem member variables for better matching with STLlloyd2009-11-171-6/+6
| | | | | | | | containers (specifically vector). Rename is_empty to empty Remove has_items Rename create to resize
* Remove the 'realname' attribute on all modules and cc/cpu/os info files.lloyd2009-10-291-2/+0
| | | | | Pretty much useless and unused, except for listing the module names in build.h and the short versions totally suffice for that.
* Increase the internal buffer size of the Hex coder/decoder, and put it intolloyd2009-10-231-3/+5
| | | | | | | | | | | | | | a named constant instead of being magic. Move from 64 bytes to 256. This was necessary to allow Pipe(new Hex_Decoder, filter, ...) to give filter a sufficiently large input block. It would be nicer if the filter itself (in this case, ECB_Decryption, but others apply as well) was smart enough to buffer on its own. It might also be useful if code could query what parallelism a block cipher provided and modify their actions accordingly.
* Add a script that reads the output of print_deps.py and rewriteslloyd2009-07-151-4/+4

* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-303-57/+63
| | | | | | | | | | | | | | | 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).
* Split the last parts of the 'core' modulelloyd2008-11-081-1/+0
| | | | Add some missing info.txts
* Split base.h into block_cipher.h and stream_cipher.hlloyd2008-11-081-0/+1
| | | | | | It turned out many files were including base.h merely to get other includes (like types.h, secmem.h, and exceptn.h). Those have been changed to directly include the files containing the declarations that code needs.

| | | | | | | | | configure.pl doesn't understand how to handle this yet (replace logic only understands stuff in src, not how one module can replace another modules src, or anything about prioritizing). Move some hex and base64 stuff out of charset.cpp and into their codec directories.
