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