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;
