* Add a function for checking if poly_double_n supports a particular sizeJack Lloyd2017-11-181-2/+1
|
* Minor SIV/CMAC optimizationsJack Lloyd2017-11-021-10/+11
|
* Make poly_dbl.h a submodule of utilsJack Lloyd2017-09-271-0/+4
| | | | | Only required by a few modules and if none of them are in use then the whole thing can just be skipped from the build.
* Better tests for SIVJack Lloyd2017-09-242-5/+8
| | | | | | | | | | | | Correct errors in the AEAD tests that assumed process/update always return something - that isn't true for SIV Minor optimizations in CMAC and CTR to cache the block size instead of making a zillion virtual calls for it. Generalize SIV slightly to where it could support a non-128 bit cipher, but don't pull the trigger on it since I can't find any implementations to crosscheck with.
* Change header guard format to BOTAN_FOO_H_Jack Lloyd2017-09-201-2/+2
| | | | | | ISO C++ reserves names with double underscores in them Closes #512
* Add API stability annotations.Jack Lloyd2017-09-191-1/+1
| | | | | Defined in build.h, all equal to BOTAN_DLL so ties into existing system for exporting symbols.
* Simplify polynomial doubling codeJack Lloyd2017-09-051-5/+3
| | | | | | | | | | GCC and Clang generate effectively identical code for a template with parameters, vs completely unrolled code as was used previously. Add a little-endian variant so XTS can use it. This extends XTS support to cover 256 and 512-bit ciphers. I was not able to find another implementation that supports both XTS and ciphers with large blocks, so the XTS test vectors are self-generated.
* Improve polynomial doubling code, move to utilJack Lloyd2017-08-151-36/+6
| | | | | | | | | Now does 64-bits at a time instead of 8 bits, and avoids conditional timing channel on the XOR carry. Confirmed that at least GCC 7 and Clang 4 on x86-64 compile the functions without conditional jumps. Also removes CMAC as a dependency of OCB, which only needed it in order to call CMAC::poly_double
* Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-021-1/+3

* Convert to using standard uintN_t integer typesJack Lloyd2016-12-182-12/+12
| | | | | | Renames a couple of functions for somewhat better name consistency, eg make_u32bit becomes make_uint32. The old typedefs remain for now since probably lots of application code uses them.
* Remove Algo_RegistryJack Lloyd2016-10-212-12/+0
| | | | | | | I repent my use of global constructors. I repent my use of global locks. Hopefully I will never touch this code again. :)

* Add final attribute to many classesJack Lloyd2016-01-101-1/+1
| | | | | | | In some cases this can offer better optimization, via devirtualization. And it lets the user know the class is not intended for derivation. Some discussion in GH #402
* Reroot the exception hierarchy into a toplevel Exception classJack Lloyd2015-12-111-1/+1
| | | | | | | | As the alternatives are unfortunate for applications trying to catch all library errors, and it seems deriving from std::runtime_error causes problems with MSVC DLLs (GH #340) Effectively reverts 2837e915d82e43
* Remove use of lookup.h in favor of new T::create API.Jack Lloyd2015-09-211-3/+2

* Internal header cleanupsJack Lloyd2015-09-191-1/+0
| | | | Only user-visible change is the removal of get_byte.h
* Handle dependencies re static linking. GH #279Jack Lloyd2015-09-171-0/+1
| | | | | | | | | | | | | | Previously we were hanging on the type destructors to pull in the relevant objects. However that fails in many simple cases where the object is never deleted. For every type involved in the algo registry add static create and providers functions to access the algo registry. Modify lookup.h to be inline and call those functions, and move a few to sub-headers (eg, get_pbkdf going to pbkdf.h). So accessing the registry involves going through the same file that handles the initialization, so there is no way to end up with missing objs.
* Fix static lib registration for block, hash, mac, stream, kdfJack Lloyd2015-09-101-2/+0
| | | | | | | | | | | The support problems from having static libraries not work in the obvious way will be endless trouble. Instead have each set of registrations tag along in a source file for the basic type, at the cost of some extra ifdefs. On shared libs this is harmless - everything is going into the shared object anyway. With static libs, this means pulling in a single block cipher pulls in the text of all the them. But that's still strictly better than the amalgamation (which is really pulling in everything), and it works (unlike status quo).

| | | | Github pull 74 from Chris Desjardins
* Add BOTAN_DLL back to LibraryInitializer and move some of the implementation tolloyd2015-03-111-1/+1
| | | | | | | a source file. Without BOTAN_DLL the LibraryInitializer was removed entirely from the list of symbols which is not desired. Add some casts to avoid scary sounding but (upon review) harmless warnings from MSVC
* Hide Algorithm_Factory and use the functions in lookup.h internally.lloyd2015-03-041-1/+4
| | | | | | Fix two memory leaks (in TLS and modes) caused by calling get_foo and then cloning the result before saving it (leaking the original object), a holdover from the conversion between construction techniques in 1.11.14

* Ensure all files have copyright and license info.lloyd2015-01-102-2/+2
| | | | | Update license header line to specify the terms and refer to the file, neither of which it included before.
* Replace Transformatio::nstart with start_raw so we can do a full setlloyd2014-11-051-0/+2

* Add the CMAC constants for 256 and 512 bit block cipherslloyd2014-02-021-6/+28
