14 | * IMPLEMENTATION NOTES. |
---|
15 | * |
---|
16 | * As you might have noticed 32-bit hash algorithms: |
---|
17 | * |
---|
18 | * - permit SHA_LONG to be wider than 32-bit (case on CRAY); |
---|
19 | * - optimized versions implement two transform functions: one operating |
---|
20 | * on [aligned] data in host byte order and one - on data in input |
---|
21 | * stream byte order; |
---|
22 | * - share common byte-order neutral collector and padding function |
---|
23 | * implementations, ../md32_common.h; |
---|
24 | * |
---|
25 | * Neither of the above applies to this SHA-512 implementations. Reasons |
---|
26 | * [in reverse order] are: |
---|
27 | * |
---|
28 | * - it's the only 64-bit hash algorithm for the moment of this writing, |
---|
29 | * there is no need for common collector/padding implementation [yet]; |
---|
30 | * - by supporting only one transform function [which operates on |
---|
31 | * *aligned* data in input stream byte order, big-endian in this case] |
---|
32 | * we minimize burden of maintenance in two ways: a) collector/padding |
---|
33 | * function is simpler; b) only one transform function to stare at; |
---|
34 | * - SHA_LONG64 is required to be exactly 64-bit in order to be able to |
---|
35 | * apply a number of optimizations to mitigate potential performance |
---|
36 | * penalties caused by previous design decision; |
---|
37 | * |
---|
38 | * Caveat lector. |
---|
39 | * |
---|
40 | * Implementation relies on the fact that "long long" is 64-bit on |
---|
41 | * both 32- and 64-bit platforms. If some compiler vendor comes up |
---|
42 | * with 128-bit long long, adjustment to sha.h would be required. |
---|
43 | * As this implementation relies on 64-bit integer type, it's totally |
---|
44 | * inappropriate for platforms which don't support it, most notably |
---|
45 | * 16-bit platforms. |
