 /*

  * IMPLEMENTATION NOTES.

  *

  * As you might have noticed 32-bit hash algorithms:

  *

  * - permit SHA_LONG to be wider than 32-bit (case on CRAY);

  * - 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.
