* Add checks that keyed algorithms are actually keyed before useJack Lloyd2017-10-261-1/+5
| | | | | Previously calling update or encrypt without calling set_key first would result in invalid outputs or else crashing.
* Add compile-time rotation functionsJack Lloyd2017-10-121-6/+6
| | | | | | | | | | | | | | | | | 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.
* 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.
* Fix various MSVC warningsJack Lloyd2017-08-311-1/+2
| | | | Based on VC2017 output
* Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-021-1/+3

* Convert to using standard uintN_t integer typesJack Lloyd2016-12-182-18/+18
| | | | | | 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.
* fix SipHash::clear() and MAC test improvementsDaniel Neus2016-07-201-3/+4
| | | | | | | | Fix for SipHash::clear() which does not clear the complete state. Test additions: - add a test for MessageAuthenticationCode::verify_mac() - test MessageAuthenticationCode::clear()
* 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
* Internal header cleanupsJack Lloyd2015-09-191-1/+0
| | | | Only user-visible change is the removal of get_byte.h
* 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).
* mac: Add missing overridesDaniel Seither2015-07-301-8/+8

* 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.
* Use registry for streams and MACs. Start updating callers.lloyd2015-01-311-3/+3
