libsodium-1.0.16-3.1

- Enable verbose make output when building tests

- Update to 1.0.16
  * Signatures computations and verifications are now way faster
    on 64-bit platforms with compilers supporting 128-bit
    arithmetic (gcc, clang, icc). This includes the WebAssembly
    target.
  * New low-level APIs for computations over edwards25519:
    crypto_scalarmult_ed25519(), crypto_scalarmult_ed25519_base(),
    crypto_core_ed25519_is_valid_point(), crypto_core_ed25519_add(),
    crypto_core_ed25519_sub() and crypto_core_ed25519_from_uniform()
    (elligator representative to point).
  * crypto_sign_open(), crypto_sign_verify_detached() and
    crypto_sign_edwards25519sha512batch_open` now reject public
    keys in non-canonical form in addition to low-order points.
  * The library can be built with ED25519_NONDETERMINISTIC defined
    in order to use synthetic nonces for EdDSA. This is disabled
    by default.
  * sodium_stackzero() was added to wipe content off the stack.
  * The Salsa20-based PRNG example is now thread-safe on platforms
    with support for thread-local storage, optionally mixes bits
    from RDRAND.
  * Argon2 and scrypt are slightly faster on Linux.

- Refresh spec-file.
- Update to 1.0.15.
  * Release notes: https://github.com/jedisct1/libsodium/releases/tag/1.0.15
  * The default password hashing algorithm is now Argon2id.
  * The pwhash_str_verify() function can still verify Argon2i hashes without any changes,
    and pwhash() can still compute Argon2i hashes as well.
  * The aes128ctr primitive was removed. It was slow, non-standard, not authenticated,
    and didn't seem to be used by any opensource project.
  * Argon2id required at least 3 passes like Argon2i, despite a minimum of 1
    as defined by the OPSLIMIT_MIN constant. This has been fixed.
  * The secretstream construction was slightly changed to be consistent with forthcoming variants.
  * The Javascript and Webassembly versions have been merged, and the module now returns
    a .ready promise that will resolve after the Webassembly code is loaded and compiled.
  * Note that due to these incompatible changes, the library version major was bumped up.

- Update to version 1.0.14
  * Internal consistency checks failing and primitives used with
    dangerous/out-of-bounds/invalid parameters used to call abort(3).
    Now, a custom handler that doesn't return can be set with the
    set_sodium_misuse() function. It still aborts by default or if
    the handler ever returns. This is not a replacement for non-fatal,
    expected runtime errors. This handler will be only called in
    unexpected situations due to potential bugs in the library or in
    language bindings.
  * *_MESSAGEBYTES_MAX macros (and the corresponding _messagebytes_max()
    symbols) have been added to represent the maximum message size that
    can be safely handled by a primitive. Language bindings are
    encouraged to check user inputs against these maximum lengths.
  * The test suite has been extended to cover more edge cases.
  * crypto_sign_ed25519_pk_to_curve25519() now rejects points that
    are not on the curve, or not in the main subgroup.
  * Further changes have been made to ensure that smart compilers
    will not optimize out code that we don't want to be optimized.
  * The sodium_runtime_has_* symbols for CPU features detection are
    now defined as weak symbols, i.e. they can be replaced with an
    application-defined implementation. This can be useful to
    disable AVX* when temperature/power consumption is a concern.
  * crypto_kx_*() now aborts if called with no non-NULL pointers
    to store keys to.
  * SSE2 implementations of crypto_verify_*() have been added.
  * Passwords can be hashed using a specific algorithm with the new
    crypto_pwhash_str_alg() function.
  * Due to popular demand, base64 encoding (sodium_bin2base64())
    and decoding (sodium_base642bin()) have been implemented.
  * A new crypto_secretstream_*() API was added to safely encrypt
    files and multi-part messages.
  * The sodium_pad() and sodium_unpad() helper functions have been
    added in order to add & remove padding.
  * An AVX512 optimized implementation of Argon2 has been added.
  * The crypto_pwhash_str_needs_rehash() function was added to check
    if a password hash string matches the given parameters, or if it
    needs an update.
  Updates from 1.0.13
  * An AVX2 optimized implementation of the Argon2 round function was added.
  * The Argon2id variant of Argon2 has been implemented. The high-level
    crypto_pwhash_str_verify() function automatically detects the
    algorithm and can verify both Argon2i and Argon2id hashed passwords.
    The default algorithm for newly hashed passwords remains Argon2i
    in this version to avoid breaking compatibility with verifiers
    running libsodium <= 1.0.12.
  * A crypto_box_curve25519xchacha20poly1305_seal*() function set was implemented.

- Update to version 1.0.12
  * Ed25519ph was implemented, adding a multi-part signature API
    (crypto_sign_init(), crypto_sign_update(), crypto_sign_final_*()).
  * New constants and related accessors have been added for Scrypt
    and Argon2.
  * XChaCha20 has been implemented. Like XSalsa20, this construction
    extends the ChaCha20 cipher to accept a 192-bit nonce. This
    makes it safe to use ChaCha20 with random nonces.
  * crypto_secretbox, crypto_box and crypto_aead now offer variants
    leveraging XChaCha20.
  * SHA-2 is about 20% faster, which also gives a speed boost to
    signature and signature verification.
  * AVX2 implementations of Salsa20 and ChaCha20 have been added.
    They are twice as fast as the SSE2 implementations. The speed
    gain is even more significant on Windows, that previously
    didn't use vectorized implementations.
  * New high-level API: crypto_kdf, to easily derive one or more
    subkeys from a master key.
  * Siphash with a 128-bit output has been implemented, and is
    available as crypto_shorthash_siphashx_*.
  * New *_keygen() helpers functions have been added to create
    secret keys for all constructions. This improves code clarity
    and can prevent keys from being partially initialized.
  * A new randombytes_buf_deterministic() function was added to
    deterministically fill a memory region with pseudorandom data.
    This function can especially be useful to write reproducible tests.
  * A preliminary crypto_kx_*() API was added to compute shared
    session keys.
  * AVX2 detection is more reliable.

- update version 1.0.11
  * sodium_init() is now thread-safe, and can be safely called
    multiple times.
  * Better support for old gcc versions.
  * AVX2 detection was fixed, resulting in faster BLAKE2b hashing
    on platforms where it was not properly detected.
  * The Sandy2x Curve25519 implementation was not as fast as
    expected on some platforms. This has been fixed.
  * The NativeClient target was improved. Most notably, it now
    supports optimized implementations, and uses pepper_49 by default.
  * The library can be compiled with recent Emscripten versions.
    Changes have been made to produce smaller code, and the default
    heap size was reduced in the standard version.
  * Decryption functions can now accept a NULL pointer for the output.
    This checks the MAC without writing the decrypted message.
  * crypto_generichash_final() now returns -1 if called twice.

- Update to version 1.0.10
  * Compile fix update for older GCCs

- Update to version 1.0.9
  * A detached API was added to the ChaCha20-Poly1305 and AES256-GCM
    implementations.
  * The Argon2i password hashing function was added, and is accessible
    directly and through a new, high-level crypto_pwhash API.
    The scrypt function remains available as well.
  * A speed-record AVX2 implementation of BLAKE2b was added.
  * Countermeasures for Ed25519 signatures malleability have been
    added to match the irtf-cfrg-eddsa draft.
  * The HChaCha20 core function was implemented (crypto_core_hchacha20()).
  * No-op stubs were added for all AES256-GCM public functions even
    when compiled on non-Intel platforms.
  * crypt_generichash_blake2b_statebytes() was added.
  * New macros were added for the IETF variant of the ChaCha20-Poly1305
    construction.

- Update to version 1.0.8
  * Handle the case where the CPU supports AVX, but we are running
    on an hypervisor with AVX disabled/not supported.
  * Faster (2x) scalarmult_base() when using the ref10 implementation.

- Update to version 1.0.7
  * Sandy2x, the fastest Curve25519 implementation ever,
    has been merged in, and is automatically used on CPUs
    supporting the AVX instructions set.
  * An SSE2 optimized implementation of Poly1305 was added,
    and is twice as fast as the portable one.
  * An SSSE3 optimized implementation of ChaCha20 was added,
    and is twice as fast as the portable one.
  * Faster sodium_increment() for common nonce sizes.
  * New helper functions have been added: sodium_is_zero()
    and sodium_add().

- Follow upstream's lead and compile with -flto for > 13.2 on x86
  and x86-64.

- Update to 1.0.6
  * Optimized implementations of Blake2 have been added for modern
    Intel platforms. crypto_generichash() is now faster than MD5 and
    SHA1 implementations while being far more secure.
  * The crypto_sign_edwards25519sha512batch_*() functions have been
    tagged as deprecated.
  * sodium_compare() now works as documented, and compares numbers
    in little-endian format instead of behaving like memcmp().
  * sodium_runtime_has_ssse3() and sodium_runtime_has_sse41() have
    been added.

- Now that gcc 5.2 is available on TW, remove the ARMv7 workaround.

- Update to 1.0.4
  * Support for AES256-GCM has been added. This requires a CPU with
    the aesni and pclmul extensions, and is accessible via the
    crypto_aead_aes256gcm_*() functions.
  * ChaCha20 with an extended (96 bit) nonce and a 32-bit counter has
    been implemented as crypto_stream_chacha20_ietf(),
    crypto_stream_chacha20_ietf_xor() and crypto_stream_chacha20_ietf_xor_ic().
    An IETF-compatible version of ChaCha20Poly1305 is available as
    crypto_aead_chacha20poly1305_ietf_npubbytes(),
    crypto_aead_chacha20poly1305_ietf_encrypt() and
    crypto_aead_chacha20poly1305_ietf_decrypt().
  * The sodium_increment() helper function has been added, to increment
    an arbitrary large number (such as a nonce).
  * The sodium_compare() helper function has been added, to compare
    arbitrary large numbers (such as nonces, in order to prevent replay attacks).

- Update to 1.0.3
  * In addition to sodium_bin2hex(), sodium_hex2bin() is now a
    constant-time function.
  * crypto_stream_xsalsa20_ic() has been added.
  * crypto_generichash_statebytes(), crypto_auth_*_statebytes()
    and crypto_hash_*_statebytes() have been added in order to
    retrieve the size of structures keeping states from foreign
    languages.
  * The JavaScript target doesn't require /dev/urandom or an
    external randombytes() implementation any more. Other minor
    Emscripten-related improvements have been made in order to
    support libsodium.js
  * Custom randombytes implementations do not need to provide
    their own implementation of randombytes_uniform() any more.
    randombytes_stir() and randombytes_close() can also be NULL
    pointers if they are not required.
  * On Linux, getrandom(2) is being used instead of directly
    accessing /dev/urandom, if the kernel supports this system
    call.
  * crypto_box_seal() and crypto_box_seal_open() have been added.
  * A solutions for Visual Studio 2015 was added.

- Update to version 1.0.2
  * The _easy and _detached APIs now support precalculated keys
  * sodium_free() can now be called on regions with PROT_NONE
    protection.
  * Memory allocation functions can now be used on operating systems
    with no memory protection.

  * crypto_sign() properly works with overlapping regions again.
  * The test suite has been extended.

- Update to version 0.7.0
  * Added sodium_malloc() and sodium_allocarray() for secure memory
    allocation.
  * ed25519 keys can be converted to curve25519 keys with
    crypto_sign_ed25519_pk_to_curve25519() and
    crypto_sign_ed25519_sk_to_curve25519().
  * aes256 was removed.
