| /* 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; */ |
