/*-
* IMPLEMENTATION NOTES.
*
* As you might have noticed 32-bit hash algorithms:
*
* - permit SHA_LONG to be wider than 32-bit
* - optimized versions implement two transform functions: one operating
* on [aligned] data in host byte order and one - on data in input
* stream byte order;
* - share common byte-order neutral collector and padding function
* implementations, ../md32_common.h;
*
* Neither of the above applies to this SHA-512 implementations. Reasons
* [in reverse order] are:
*
* - it's the only 64-bit hash algorithm for the moment of this writing,
* there is no need for common collector/padding implementation [yet];
* - by supporting only one transform function [which operates on
* *aligned* data in input stream byte order, big-endian in this case]
* we minimize burden of maintenance in two ways: a) collector/padding
* function is simpler; b) only one transform function to stare at;
* - SHA_LONG64 is required to be exactly 64-bit in order to be able to
* apply a number of optimizations to mitigate potential performance
* penalties caused by previous design decision;
*
* Caveat lector.
*
* Implementation relies on the fact that "long long" is 64-bit on
* both 32- and 64-bit platforms. If some compiler vendor comes up
* with 128-bit long long, adjustment to sha.h would be required.
* As this implementation relies on 64-bit integer type, it's totally
* inappropriate for platforms which don't support it, most notably
* 16-bit platforms.
