| /* IMPLEMENTATION NOTES. |
| * |
| * The 32-bit hash algorithms share a common byte-order neutral collector and |
| * padding function implementations that operate on unaligned data, |
| * ../md32_common.h. This SHA-512 implementation does not. 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 a transform function that operates on *aligned* data |
| * the collector/padding function is simpler and easier to optimize. */ |
