* Fixes for minimized buildsJack Lloyd2019-02-161-1/+1
| | | | Various configurations would fail build or test, fix that.
* Avoid including rotate.h in bswap.hJack Lloyd2018-12-211-0/+1
| | | | | | | It was only needed for one case which is easily hardcoded. Include rotate.h in all the source files that actually use rotr/rotl but implicitly picked it up via loadstor.h -> bswap.h -> rotate.h include chain.
* Add explicit AVX2 function annotationsJack Lloyd2018-10-051-0/+2
| | | | Needed for single amalagamation file with AVX2 enabled.
* Report if Serpent is using AVX2Jack Lloyd2018-09-101-0/+7

* Serpent 8x decryptJack Lloyd2018-08-241-1/+1

* WIP for Serpent AVX2Jack Lloyd2018-08-241-0/+26

* Add checks that keyed algorithms are actually keyed before useJack Lloyd2017-10-261-0/+4
| | | | | Previously calling update or encrypt without calling set_key first would result in invalid outputs or else crashing.
* Add compile-time rotation functionsJack Lloyd2017-10-121-11/+11
| | | | | | | | | | | | | | | | | The problem with asm rol/ror is the compiler can't schedule effectively. But we only need asm in the case when the rotation is variable, so distinguish the two cases. If a compile time constant, then static_assert that the rotation is in the correct range and do the straightforward expression knowing the compiler will probably do the right thing. Otherwise do a tricky expression that both GCC and Clang happen to have recognize. Avoid the reduction case; instead require that the rotation be in range (this reverts 2b37c13dcf). Remove the asm rotations (making this branch illnamed), because now both Clang and GCC will create a roll without any extra help. Remove the reduction/mask by the word size for the variable case. The compiler can't optimize that it out well, but it's easy to ensure it is valid in the callers, especially now that the variable input cases are easy to grep for.
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-181-12/+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.
* Add Cilk/OpenMP supportJack Lloyd2016-11-261-34/+47

* Change T::provider to return std::stringJack Lloyd2016-09-151-1/+1
|
* Add T::provider() to allow user to inquire about implementation usedJack Lloyd2016-09-151-0/+12
| | | | | For block ciphers, stream ciphers, hashes, MACs, and cipher modes. Cipher_Mode already had it, with a slightly different usage.
* Merge optimized implementations into base classJack Lloyd2016-09-151-0/+30
| | | | | | | | | | Various algorithms had an optimized implementation (for SSE2, AVX2, etc) which was offered alongside the 'base' implementation. This is admittedly very useful for testing, but it breaks user expectations in bad ways. See GH #477 for background. Now encrypting with `AES_128` (say) just runs whatever implementation is best on the current processor/build.
* Mass-prefix member vars with m_René Korthaus2016-01-081-6/+6

* Fix static lib registration for block, hash, mac, stream, kdfJack Lloyd2015-09-101-3/+1
| | | | | | | | | | | 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).
* More changes for use with debug STLSimon Warta2015-06-301-1/+1

* Add a runtime map of string->func() which when called returnlloyd2015-01-281-4/+5
| | | | | | | | | | | | | | | | | Transforms and BlockCiphers. Registration for all types is done at startup but is very cheap as just a std::function and a std::map entry are created, no actual objects are created until needed. This is a huge improvement over Algorithm_Factory which used T::clone() as the function and thus kept a prototype object of each type in memory. Replace existing lookup mechanisms for ciphers, AEADs, and compression to use the transform lookup. The existing Engine framework remains in place for BlockCipher, but the engines now just call to the registry instead of having hardcoded lookups. s/Transformation/Transform/ with typedefs for compatability. Remove lib/selftest code (for runtime selftesting): not the right approach.
* Ensure all files have copyright and license info.lloyd2015-01-101-1/+1
| | | | | Update license header line to specify the terms and refer to the file, neither of which it included before.
* Move lib into srclloyd2014-01-101-0/+205
