We recently learned our Simon and Speck implementation was wrong. The removal will stop harm until we can loop back and fix the issue.
The issue is, the paper, the test vectors and the ref-impl do not align. Each produces slightly different result. We followed the test vectors but they turned out to be wrong for the ciphers.
We have one kernel test vector but we don't have a working implementation to observe it to fix our implementation. Ugh...
This reverts commit eb3b27a6a5. The change broke GCC 4.8 and unknown version of Clang on OS X. UB reported the OS X break, and JW found duplicated the break on a ARM CubieTruck with GCC 4.8.
CRYPTOPP_COVERAGE was added at 9614307ab7 to increase code coverage support. This commit enables additional validation routines when CRYPTOPP_COVERAGE is in effect.
regtest.cpp is where ciphers register by name. The library has added a number of ciphers over the last couple of years and the source file has experienced bloat. Most of the ARM and MIPS test borads were suffering Out of Memory (OOM) kills as the compiler processed the source fille and the included header files.
This won't stop the OOM kills, but it will help the situation. An early BeagleBoard with 512 MB of RAM is still going to have trouble, but it can be worked around by building with 1 make job as opposed to 2 or 4.
