* Make stream, block, hash and cipher mode base classes optionalJack Lloyd2018-01-121-1/+1
|
* Remove needless virtual on GMAC destructorJack Lloyd2017-10-261-1/+1
|
* GCM and CTR optimizationsJack Lloyd2017-10-182-6/+15
| | | | | | | | | | | In CTR, special case for counter widths of special interest. In GHASH, uses a 4x reduction technique suggested by Intel. Split out GHASH to its own source file and header. With these changes GCM is over twice as fast on Skylake and about 50% faster on Westmere.
* GMAC optimizationJack Lloyd2017-10-152-21/+32
| | | | | Avoid copying inputs needlessly, on Skylake doubles performance (from 1 GB/s -> 2 GB/s)
* Optimize GCMJack Lloyd2017-10-132-23/+27
| | | | | | | | | | By allowing multiple blocks for clmul, slight speedup there though still far behind optimum. Precompute a table of multiples of H, 3-4x faster on systems without clmul (and still no secret indexes). Refactor GMAC to not derive from GHASH
* Avoid bogus declarations in GMACJack Lloyd2017-09-301-25/+3
| | | | | These functions are declared/defined on MessageAuthenticationCode, and call the start_msg virtual.
* Address some MSVC warningsJack Lloyd2017-09-301-4/+3
|
* Apply final annotations to the library alsoJack Lloyd2017-09-221-1/+1
| | | | | Done by a perl script which converted all classes to final, followed by selective reversion where it caused compilation failures.
* More include header cleanupsJack Lloyd2017-09-211-0/+1
|
* Header file cleanupsJack Lloyd2017-09-211-6/+2
| | | | Some help from include-what-you-use
* 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.
* Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-021-1/+3
|
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-182-15/+15
| | | | | | 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 MAC::start_msg, update GMACJack Lloyd2016-10-282-14/+4
| | | | | | | | GMAC needs a per-message nonce specified with `start`, and other MACs are capable of using nonces (Skein-MAC, for instance) so move this API up to MAC class. Change GMAC::clone to clone the owned cipher.
* Implements GMAC with GHASH.Matthias Gierlings2016-10-282-44/+98
| | | | | Adds support for Galois Message Authentication Code calculation based on GHASH, rather than GCM_Mode.
* Added implementation for GMACMatthias Gierlings2016-10-273-0/+159
- Added GMAC class - Integrated GMAC into MAC-Class test bench. Run GMAC tests using ./botan-test mac
