AP		 10 * IMPLEMENTATION NOTES.
11 *
12 * As you might have noticed 32-bit hash algorithms:
13 *
14 * - permit SHA_LONG to be wider than 32-bit (case on CRAY);
15 * - optimized versions implement two transform functions: one operating
16 * on [aligned] data in host byte order and one - on data in input
17 * stream byte order;
18 * - share common byte-order neutral collector and padding function
19 * implementations, ../md32_common.h;
20 *
21 * Neither of the above applies to this SHA-512 implementations. Reasons
22 * [in reverse order] are:
23 *
24 * - it's the only 64-bit hash algorithm for the moment of this writing,
25 * there is no need for common collector/padding implementation [yet];
26 * - by supporting only one transform function [which operates on
27 * *aligned* data in input stream byte order, big-endian in this case]
28 * we minimize burden of maintenance in two ways: a) collector/padding
29 * function is simpler; b) only one transform function to stare at;
30 * - SHA_LONG64 is required to be exactly 64-bit in order to be able to
31 * apply a number of optimizations to mitigate potential performance
32 * penalties caused by previous design decision;
33 *
34 * Caveat lector.
35 *
36 * Implementation relies on the fact that "long long" is 64-bit on
37 * both 32- and 64-bit platforms. If some compiler vendor comes up
38 * with 128-bit long long, adjustment to sha.h would be required.
39 * As this implementation relies on 64-bit integer type, it's totally
40 * inappropriate for platforms which don't support it, most notably
41 * 16-bit platforms.
