14 * IMPLEMENTATION NOTES.
15 *
16 * As you might have noticed 32-bit hash algorithms:
17 *
18 * - permit SHA_LONG to be wider than 32-bit (case on CRAY);
19 * - optimized versions implement two transform functions: one operating
20 * on [aligned] data in host byte order and one - on data in input
21 * stream byte order;
22 * - share common byte-order neutral collector and padding function
23 * implementations, ../md32_common.h;
24 *
25 * Neither of the above applies to this SHA-512 implementations. Reasons
26 * [in reverse order] are:
27 *
28 * - it's the only 64-bit hash algorithm for the moment of this writing,
29 * there is no need for common collector/padding implementation [yet];
30 * - by supporting only one transform function [which operates on
31 * *aligned* data in input stream byte order, big-endian in this case]
32 * we minimize burden of maintenance in two ways: a) collector/padding
33 * function is simpler; b) only one transform function to stare at;
34 * - SHA_LONG64 is required to be exactly 64-bit in order to be able to
35 * apply a number of optimizations to mitigate potential performance
36 * penalties caused by previous design decision;
37 *
38 * Caveat lector.
39 *
40 * Implementation relies on the fact that "long long" is 64-bit on
41 * both 32- and 64-bit platforms. If some compiler vendor comes up
42 * with 128-bit long long, adjustment to sha.h would be required.
43 * As this implementation relies on 64-bit integer type, it's totally
44 * inappropriate for platforms which don't support it, most notably
45 * 16-bit platforms.
