* Change T::provider to return std::stringJack Lloyd2016-09-151-2/+1
|
* Add T::provider() to allow user to inquire about implementation usedJack Lloyd2016-09-151-0/+7
| | | | | 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 Lloyd2016-09-156-75/+47
| | | | | | | | | | 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.

| * Add NEWHOPE KEM schemeJack Lloyd2016-08-302-6/+9
| | | | | | | | | | | | | | | | | | | | Provides conjectured 200-bit security against a quantum attacker. Based on the public domain reference implementation at https://github.com/tpoeppelmann/newhope and bit-for-bit compatible with that version. Test vectors generated by the reference testvector.c

* improve parallel hash tests + memory leak fixDaniel Neus2016-07-201-1/+1
| | | | | | | | | | - add one test with SHA-256,SHA-512 - test Parallel::clone() - test Parallel ctor - fix memory leak in Parallel::clone(): Currently Parallel::clone() calls hash->clone() (first heap allocation) and after this clone() calls Parallel(const std::vector<HashFunction*>& in) which does another heap allocation. So its sufficient to pass the hash pointer to the Parallel ctor instead of a clone

* Order the accesses to A[] in the Keccak permutation.Jack Lloyd2016-02-061-17/+17
| | | | | | Consistent speed up of about ~5% on my machine. Also tried moving all the A[] values to local registers, was slower.

* Add final attribute to many classesJack Lloyd2016-01-1019-26/+28
| | | | | | | 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
* Mass-prefix member vars with m_René Korthaus2016-01-0837-704/+704
|
* Merge the openssl code together.Jack Lloyd2015-12-192-122/+0
| | | | | | | Having the code diffused all over the place was ugly and would not scale well to multiple alternative providers. GH #368
* Missing addsJack Lloyd2015-12-111-1/+1
|
* Reroot the exception hierarchy into a toplevel Exception classJack Lloyd2015-12-111-2/+2
| | | | | | | | 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
* Update and consolidate the test framework.Jack Lloyd2015-11-111-1/+1
| | | | | | | | | | | The tests previously had used 4 to 6 different schemes internally (the vec file reader framework, Catch, the old InSiTo Boost.Test tests, the PK/BigInt tests which escaped the rewrite in 1.11.7, plus a number of one-offs). Converge on a design that works everywhere, and update all the things. Fix also a few bugs found by the test changes: SHA-512-256 name incorrect, OpenSSL RC4 name incorrect, signature of FFI function botan_pubkey_destroy was wrong.
* Break up openssl providerJack Lloyd2015-10-192-0/+122
| | | | | | For RSA, RC4, and ECDSA put the openssl versions in the same directory as the base version. They just rely on a macro check for the openssl module to test for the desire to use OpenSSL.
* Address some review comments by Simon. GH #279Jack Lloyd2015-09-211-1/+1

* Internal header cleanupsJack Lloyd2015-09-1923-63/+17
| | | | Only user-visible change is the removal of get_byte.h
* Handle dependencies re static linking. GH #279Jack Lloyd2015-09-174-4/+31
| | | | | | | | | | | | | | 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 Lloyd2015-09-1022-46/+184
| | | | | | | | | | | 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).
* Remove alloc module; move secmem.h to base and locking_allocator to utilsJack Lloyd2015-08-291-4/+0
|
* Reverse the algorithm priority orderingJack Lloyd2015-08-291-1/+2
| | | | | | Previously 0 was the highest priority and 255 was the lowest. But this is really quite confusing, instead treat 0 as lowest and 255 as highest so normal integer intuitions apply.
* hash: Add missing overridesDaniel Seither2015-07-3021-143/+143
|
* Remove the x86 asm versions of MD4, MD5, SHA-1 and SerpentJack Lloyd2015-07-2516-1115/+0
| | | | | | | With modern compilers, all are slower than the C++ and SSE2 versions of the same algos. GH #216

* In Algo_Registry if a maker func fails, try the next most preferred onelloyd2015-03-051-1/+1
| | | | | | | | instead of bailing out immediately. Rename the 'builtin' provider to 'base' since really they are all built in. Fix MARK-4 when OpenSSL was enabled - it did not respect the skip param.
* Hide Algorithm_Factory and use the functions in lookup.h internally.lloyd2015-03-042-8/+3
| | | | | | 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

* Remove algo factory, engines, global RNG, global state, etc.lloyd2015-02-046-13/+7
| | | | | | | | | | | | | | | Convert all uses of Algorithm_Factory and the engines to using Algo_Registry The shared pool of entropy sources remains but is moved to EntropySource. With that and few remaining initializations (default OIDs and aliases) moved elsewhere, the global state is empty and init and shutdown are no-ops. Remove almost all of the headers and code for handling the global state, except LibraryInitializer which remains as a compatability stub. Update seeding for blinding so only one hacky almost-global RNG instance needs to be setup instead of across all pubkey uses (it uses either the system RNG or an AutoSeeded_RNG if the system RNG is not available).
* Add missing files. Remove cipher lookup from engine code.lloyd2015-02-011-0/+33
