Reasons 22 * [in reverse order] are: 23 * 24 * - it's the only 64-bit hash algorithm for the moment of this writing, 25 * there is no need for common collector/padding implementation [yet]; 26 * - by supporting only one transform function [which operates on 27 * *aligned* data in input stream byte order, big-endian in this case] 28 * we minimize burden of maintenance in two ways: a) collector/padding 29 * function is simpler; b) only one transform function to stare at; 30 * - SHA_LONG64 is required to be exactly 64-bit in order to be able to 31 * apply a number of optimizations to mitigate potential performance 32 * penalties caused by previous design decision; 33 * 34 * Caveat lector. 35 * 36 * Implementation relies on the fact that "long long" is 64-bit on 37 * both 32- and 64-bit platforms. If some compiler vendor comes up 38 * with 128-bit long long, adjustment to sha.h would be required. 39 * As this implementation relies on 64-bit integer type, it's totally 40 * inappropriate for platforms which don't support it, most notably 41 * 16-bit platforms. 42 * <appro@fy.chalmers.se> 43 */ 44#include <stdlib.h> 45#include <string.h> 46 47#include <openssl/crypto.h> 48#include <openssl/sha.h> 49#include <openssl/opensslv.h> 50 51#include "cryptlib.h" 52 53const char SHA512_version[]="SHA-512" OPENSSL_VERSION_PTEXT;
