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. * <appro@fy.chalmers.se> */ #include <stdlib.h> #include <string.h> #include <openssl/crypto.h> #include <openssl/sha.h> #include <openssl/opensslv.h> #include "cryptlib.h" const char SHA512_version[]="SHA-512" OPENSSL_VERSION_PTEXT;
