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.
