|

| 12 | * IMPLEMENTATION NOTES.
|
|---|
| 13 | *
|
|---|
| 14 | * As you might have noticed 32-bit hash algorithms:
|
|---|
| 15 | *
|
|---|
| 16 | * - permit SHA_LONG to be wider than 32-bit
|
|---|
| 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.
