Well, the IBM docs were not quite correct when they stated "The block is aligned so that it can be used for any type of data". The vector data types are pretty standard, even across different machines from diffent manufacturers
Enable aligned allocations under IBM XL C/C++. Based on the AIX malloc man pages, "... the block is aligned so that it can be used for any type of data". Previously CRYPTOPP_NO_ALIGNED_ALLOC was in effect.
Use malloc instead of calloc on OS X. Based on the OS X malloc man pages, "... the allocated memory is aligned such that it can be used for any data type, including AltiVec- and SSE-related types". Additionally, calloc zero'd the memory it allocated which slowed things down on Apple systems.
StringWiden converts a narrow C-style string to a wide string. It serves the opposite role of StringNarrow function. The function is useful on Windows platforms where the OS favors wide functions with the UTF-16 character set. For example, the Data Proction API (DPAPI) allows a description, but its a wide character C-string. There is no narrwo version of the API.
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
- added AuthenticatedSymmetricCipher interface class and Filter wrappers
- added CCM, GCM (with SSE2 assembly), CMAC, and SEED
- improved AES speed on x86 and x64
- removed WORD64_AVAILABLE; compiler 64-bit int support is now required
