* Add checks that keyed algorithms are actually keyed before useJack Lloyd2017-10-262-0/+10
| | | | | Previously calling update or encrypt without calling set_key first would result in invalid outputs or else crashing.
* Skip ARM32 specific byteswap code, enable MSVC byteswap intrinsicsJack Lloyd2017-10-242-34/+15
| | | | | | | | | | While older versions of GCC did very badly with __builtin_bswap on ARM, I checked GCC 4.8 and it behaves correctly, emitting either rev or else the same optimal sequence as was used in the inline asm (depending on if ARMv7 is enabled or not.) Enable MSVC byteswap intrinsics, which (hopefully) work on all platforms. Drop the x86-32 specific asm for byteswap.

* Add a destructor to Policy_ViolationJack Lloyd2017-10-191-3/+4
| | | | | MSVC produces a deranged warning that the compiler generated destructor is deprecated, try to shut it up.

* De-inline bodies of exception classesJack Lloyd2017-10-153-67/+133
| | | | | | | | | This leads to a rather shocking decrease in binary sizes, especially the static library (~1.5 MB reduction). Saves 60KB in the shared lib. Since throwing or catching an exception is relatively expensive these not being inlined is not a problem in that sense. It had simply not occured to me that it would take up so much extra space in the binary.

| * Ugh, the GCC/Clang trick triggers C4146 under MSVCJack Lloyd2017-10-121-8/+25
| | | | | | | | | | | | And rotate.h is a visible header. Blerg. Inline asm it is.
| * Add compile-time rotation functionsJack Lloyd2017-10-123-72/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * Use rol/ror x86 instructions on GCC/ClangJack Lloyd2017-10-111-2/+24
| | | | | | | | | | | | | | Neither is very good at recognizing rotate sequences. For cases where the rotation value is a constant they do fine, but for variable rotations they do horribly. Using inline asm here improved performance of both CAST-128 and CAST-256 by ~20% on my system with both GCC and Clang.
* | Avoid std::count to skip a signed overflow warningJack Lloyd2017-10-122-3/+13
| | | | | | | | | | | | Couldn't figure out a way to silence this otherwise. Deprecate replace_char, erase_chars, replace_chars

| | | | | | | | | | It was disabled anyway (bad macro check) and with recent GCC turned out to be slower than just using bswap.

* Simplify header includes in socket.cppJack Lloyd2017-10-031-9/+3
| | | | | | This got a little contorted in os_utils.cpp because of need to support Boost asio along with system dependent interfaces. Here it's simple: Boost or Unix or Winsock.

* Add wrappers for reinterpret_cast between char* and uint8_t*Jack Lloyd2017-10-035-15/+35
| | | | | | | Generally speaking reinterpret_cast is sketchy stuff. But the special case of char*/uint8_t* is both common and safe. By isolating those, the remaining (likely sketchy) cases are easier to grep for.
