Fix bad SHA::Transform calculation (Issue 455) 
Reworked SHA class internals to align all the implementations. Formerly all hashes were software based, IterHashBase handled endian conversions, IterHashBase repeatedly called the single block SHA{N}::Transform. The rework added SHA{N}::HashMultipleBlocks, and the SHA classes attempt to always use it.

Now SHA{N}::Transform calls into SHA{N}_HashMultipleBlocks, which is a free standing function. An added wrinkle is hardware wants little endian data and software presents big endian data, so HashMultipleBlocks accepts a ByteOrder for the incoming data. Hardware based SHA{N}_HashMultipleBlocks can often perform the endian swap much easier by setting an EPI mask so it was profitable to defer to hardware when available.

The rework also removed the hacked-in pointers to implementations. The class now looks more like AES, GCM, etc.

Updated static initializers 
When MSVC init_seg or GCC init_priority is available, we don't need to use the Singleton. We only need to create a file scope class variable and place it in the segment for MSVC or provide the attribute for GCC.
An additional upside is we cleared all the memory leaks that used to be reported by MSVC for debug builds.

a33b95325f When calculating the AES block cipher, allocate 4K of memory on the stack instead of 256+ bytes. Search within that 4K space to put the 256-byte aligned Locals struct in a place which does not have 4K cache conflicts with the Te temporary buffer. This permits us to call _malloca() or alloca() once per call of this function. This commit also makes sure that the Microsoft-only _freea() occurs at the correct location instead of at a pointer to the middle of the stack, when the memory allocated by _malloca() or alloca() is not 256-byte aligned. 2016-09-22 17:43:57 -07:00

399a1546de Add CRYPTOPP_ASSERT (Issue 277, CVE-2016-7420) 
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

f43b7c95cd Check for SSE4 support before using SSE4.1 instruction 
In a 32-bit Windows program compiled with Visual C++ 2013 Update 5, we
sometimes get crashes because of an exception "0xC000001D: Illegal Instruction"
on the pextrd (_mm_extract_epi32) instruction. Explicitly check for SSE4
support instead of only AES-NI before using this SSE4.1 instruction.

ab393851ec Revert "Improve performance of fix to Issue 146" 
This reverts commit 5cce8c33ca. It was an incomplete remediation because it was applied to one area of the code, and not both areas of the code. The complete remediation will be checked-in next.
