C++ (Cpp) isc_safe_memcmp Examples

Example #1

File: safe_test.c Project: enukane/netbsd-src

ATF_TC_BODY(isc_safe_memcmp, tc) {
	UNUSED(tc);

	ATF_CHECK(isc_safe_memcmp("test", "test", 4));
	ATF_CHECK(!isc_safe_memcmp("test", "tesc", 4));
	ATF_CHECK(isc_safe_memcmp("\x00\x00\x00\x00", "\x00\x00\x00\x00", 4));
	ATF_CHECK(!isc_safe_memcmp("\x00\x00\x00\x00", "\x00\x00\x00\x01", 4));
	ATF_CHECK(!isc_safe_memcmp("\x00\x00\x00\x02", "\x00\x00\x00\x00", 4));
}

Example #2

File: hmacmd5.c Project: execunix/vinos

isc_boolean_t
isc_hmacmd5_verify2(isc_hmacmd5_t *ctx, unsigned char *digest, size_t len) {
	unsigned char newdigest[ISC_MD5_DIGESTLENGTH];

	REQUIRE(len <= ISC_MD5_DIGESTLENGTH);
	isc_hmacmd5_sign(ctx, newdigest);
	return (isc_safe_memcmp(digest, newdigest, len));
}

Example #3

File: hmacsha.c Project: SvenDowideit/clearlinux

/*
 * Verify signature - finalize SHA224 operation and reapply SHA224, then
 * compare to the supplied digest.
 */
isc_boolean_t

	unsigned char newdigest[ISC_SHA224_DIGESTLENGTH];

	REQUIRE(len <= ISC_SHA224_DIGESTLENGTH);
	isc_hmacsha224_sign(ctx, newdigest, ISC_SHA224_DIGESTLENGTH);
	return (isc_safe_memcmp(digest, newdigest, len));
