12 | * IMPLEMENTATION NOTES. |
| 13 | * | |
| 14 | * As you might have noticed 32-bit hash algorithms: | |
| 15 | * | |
| 7bf7a6d0 | 16 | * - permit SHA_LONG to be wider than 32-bit |
| 3e575651 SL |
17 | * - optimized versions implement two transform functions: one operating |
| 18 | * on [aligned] data in host byte order and one - on data in input | |
| 19 | * stream byte order; | |
| 20 | * - share common byte-order neutral collector and padding function | |
| 21 | * implementations, ../md32_common.h; | |
| 22 | * | |
| 23 | * Neither of the above applies to this SHA-512 implementations. Reasons | |
| 24 | * [in reverse order] are: | |
| 25 | * | |
| 26 | * - it's the only 64-bit hash algorithm for the moment of this writing, | |
| 27 | * there is no need for common collector/padding implementation [yet]; | |
| 28 | * - by supporting only one transform function [which operates on | |
| 29 | * *aligned* data in input stream byte order, big-endian in this case] | |
| 30 | * we minimize burden of maintenance in two ways: a) collector/padding | |
| 31 | * function is simpler; b) only one transform function to stare at; | |
| 32 | * - SHA_LONG64 is required to be exactly 64-bit in order to be able to | |
| 33 | * apply a number of optimizations to mitigate potential performance | |
| 34 | * penalties caused by previous design decision; | |
| 35 | * | |
| 36 | * Caveat lector. | |
| 37 | * | |
| 38 | * Implementation relies on the fact that "long long" is 64-bit on | |
| 39 | * both 32- and 64-bit platforms. If some compiler vendor comes up | |
| 40 | * with 128-bit long long, adjustment to sha.h would be required. | |
| 41 | * As this implementation relies on 64-bit integer type, it's totally | |
| 42 | * inappropriate for platforms which don't support it, most notably | |
| 43 | * 16-bit platforms. | |
