adhoc.cpp was a bit uncomfortable because we had to copy it out from adhoc.cpp.proto. For some reason CMake could not perform the copy, so we started using pch.cpp in CMake. This commit keeps them consistent.
We may have problems with one test, and that is the Newlib tests. I seem to recall they a C++ header included to properly identify its use. We cross that bridge during MinGW testing.
This PR adds ARMv8.4 cpu feature detection support. Previously we only needed ARMv8.1 and things were much easier. For example, ARMv8.1 `__ARM_FEATURE_CRYPTO` meant PMULL, AES, SHA-1 and SHA-256 were available. ARMv8.4 `__ARM_FEATURE_CRYPTO` means PMULL, AES, SHA-1, SHA-256, SHA-512, SHA-3, SM3 and SM4 are available.
We still use the same pattern as before. We make something available based on compiler version and/or preprocessor macros. But this time around we had to tighten things up a bit to ensure ARMv8.4 did not cross-pollinate down into ARMv8.1.
ARMv8.4 is largely untested at the moment. There is no hardware in the field and CI lacks QEMU with the relevant patches/support. We will probably have to revisit some of this stuff in the future.
Since this update applies to ARM gadgets we took the time to expand Android and iOS testing on Travis. Travis now tests more platforms, and includes Autotools and CMake builds, too.
Some distros don't want to install cryptest.exe. For folks who don't want to install the test program, they can issue 'make install-lib'.
install-lib is a non-standard target, but the GNU Coding Standard does not have a standard target for the task.
This is a convention that binary compatibity uses one number.
Using that, it's possible to have bugfixes releases (patchlevel
incremented) and enhancement release (minor incremented with no
public interface removed).
Here is more information about convention

(libtool isn't relevant to this project, but the explanation hold)

We recently learned our Simon and Speck implementation was wrong. The removal will stop harm until we can loop back and fix the issue.
The issue is, the paper, the test vectors and the ref-impl do not align. Each produces slightly different result. We followed the test vectors but they turned out to be wrong for the ciphers.
We have one kernel test vector but we don't have a working implementation to observe it to fix our implementation. Ugh...
This commit does a few things. First, it uses the compiler's triplet and the build component to determine the machine we are targeting. Second, it adds an 'X' prefix so we don't collide with someone else's variables. Third it cleans up some of the recipes. Fourth, it removes X32 detection since the system differences are handled in config.h and the source files
Fix Environment setup for android to match the new unified headers.
Adjust the Makefile accordingly.
Updated the test scripts and travis to test these changes.
TweetNaCl is a compact reimplementation of the NaCl library by Daniel J. Bernstein, Bernard van Gastel, Wesley Janssen, Tanja Lange, Peter Schwabe and Sjaak Smetsers. The library is less than 20 KB in size and provides 25 of the NaCl library functions.
The compact library uses curve25519, XSalsa20, Poly1305 and SHA-512 as default primitives, and includes both x25519 key exchange and ed25519 signatures. The complete list of functions can be found in TweetNaCl: A crypto library in 100 tweets (20140917), Table 1, page 5.
Crypto++ retained the function names and signatures but switched to data types provided by <stdint.h> to promote interoperability with Crypto++ and avoid size problems on platforms like Cygwin. For example, NaCl typdef'd u64 as an unsigned long long, but Cygwin, MinGW and MSYS are LP64 systems (not LLP64 systems). In addition, Crypto++ was missing NaCl's signed 64-bit integer i64.
Crypto++ enforces the 0-key restriction due to small points. The TweetNaCl library allowed the 0-keys to small points. Also see RFC 7748, Elliptic Curves for Security, Section 6.
TweetNaCl is well written but not well optimized. It runs 2x to 3x slower than optimized routines from libsodium. However, the library is still 2x to 4x faster than the algorithms NaCl was designed to replace.
The Crypto++ wrapper for TweetNaCl requires OS features. That is, NO_OS_DEPENDENCE cannot be defined. It is due to TweetNaCl's internal function randombytes. Crypto++ used DefaultAutoSeededRNG within randombytes, so OS integration must be enabled. You can use another generator like RDRAND to avoid the restriction.
* GNUmakefile-cross: Fix install target
The install target was not working: missing mkdir before copying files,
wrong dynamic library copied, missing ldconf.
The fix is mostly taken from the install target from GNUmakefile.
* Makefile: call 'ln -sf' instead of 'ln -sf -sf'
