66 /* IMPLEMENTATION NOTES.
67 *
68 * The 32-bit hash algorithms share a common byte-order neutral collector and
69 * padding function implementations that operate on unaligned data,
70 * ../md32_common.h. This SHA-512 implementation does not. Reasons
71 * [in reverse order] are:
72 *
73 * - It's the only 64-bit hash algorithm for the moment of this writing,
74 * there is no need for common collector/padding implementation [yet];
75 * - By supporting only a transform function that operates on *aligned* data
76 * the collector/padding function is simpler and easier to optimize. */
