* GCM and CTR optimizationsJack Lloyd2017-10-181-0/+2
| | | | | | | | | | | 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.
* Use constant_time_compare instead of same_memJack Lloyd2017-09-161-1/+1
| | | | New name, same great operation
* Add BOTAN_UNUSED in creator functionsJack Lloyd2017-01-271-0/+3
| | | | | | If all (say) stream ciphers are disabled, avoid unused arg warning. [ci skip]
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-181-2/+2
| | | | | | 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.
* Implements GMAC with GHASH.Matthias Gierlings2016-10-281-0/+11
| | | | | Adds support for Galois Message Authentication Code calculation based on GHASH, rather than GCM_Mode.
* Added implementation for GMACMatthias Gierlings2016-10-271-0/+4
| | | | | | - Added GMAC class - Integrated GMAC into MAC-Class test bench. Run GMAC tests using ./botan-test mac
* Remove alias logic from SCAN_NameJack Lloyd2016-10-211-3/+3
| | | | | | This required taking a global lock and doing a map lookup each time an algorithm was requested (and so many times during a TLS handshake).
* Remove Algo_RegistryJack Lloyd2016-10-211-31/+86
| | | | | | | I repent my use of global constructors. I repent my use of global locks. Hopefully I will never touch this code again. :)
* Remaining cppcheck fixes that are not covered by GH #444Daniel Neus2016-03-051-1/+1

* cppcheck fixes: Class 'X' has a constructor with 1 argument that is not ↵Daniel Neus2016-03-051-1/+1

* Internal header cleanupsJack Lloyd2015-09-191-4/+3
| | | | Only user-visible change is the removal of get_byte.h
* Handle dependencies re static linking. GH #279Jack Lloyd2015-09-171-0/+11
| | | | | | | | | | | | | | 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 Lloyd2015-09-101-0/+52
| | | | | | | | | | | 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).
* lib/mac: Convert &vec[0] to vec.data()Simon Warta2015-06-251-1/+1

* 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/+26
