|
* 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;
|
|
*
|
|
* Caveat lector.
|
|
*
|
|
* Implementation relies on the fact that "long long" is 64-bit on
|
|
* both 32- and 64-bit platforms. If some compiler vendor comes up
|
|
* with 128-bit long long, adjustment to sha.h would be required.
|
|
* As this implementation relies on 64-bit integer type, it's totally
|
|
* inappropriate for platforms which don't support it, most notably
|
|
* 16-bit platforms.
