This should have been checked-in during GH #783 and PR #784. I think there was one mailing list message about missing symbols GF2NT_233_Multiply_Reduce_CLMUL and GF2NT_233_Square_Reduce_CLMUL. I missed it when attempting to reproduce the issue. I can duplicate it now using VS2013. I think the addition of CRYPTOPP_DLL caused the issue to surface.
This is the reference implementation, test data and test vectors from the ARIA.zip package on the KISA website. The website is located at http://seed.kisa.or.kr/iwt/ko/bbs/EgovReferenceList.do?bbsId=BBSMSTR_000000000002.
We have optimized routines that improve Key Setup and Bulk Encryption performance, but they are not being checked-in at the moment. The ARIA team is updating its implementation for contemporary hardware and we would like to use it as a starting point before we wander too far away from the KISA implementation.
trap.h and CRYPTOPP_ASSERT has existed for over a year in Master. We deferred on the cut-over waiting for a minor version bump (5.7). We have to use it now due to CVE-2016-7420
