Merge pull request #299 from dalek-cryptography/fix-avx2-zeroize 
Fix broken build with AVX2.
 2019-10-25 15:50:11 -07:00
Henry de Valence
d0ea313e99 Remove broken impl Zeroize for FieldElement2625x4. 
This implementation is broken because the packed_simd types don't implement `Zeroize`.

Merge pull request #298 from dalek-cryptography/update-rand 
Update rand_core, rand, rand_os.
 2019-10-24 13:17:44 -07:00
Henry de Valence
6739399ec2 Upgrade to current rand_core, rand, rand_os. 
Of these only `rand_core` is included in the public API; regardless of `rand`
semver tricks, this is a breaking API change, but the major version is already
bumped to include the Serde serialization fixes.

018fccfe8c Avoid over-specific version specifiers. 
By default, Cargo treats version specifiers as semver-compatible ranges, so the
version specifiers we include should only have the components that are actually
meaningful, e.g., "1" instead of "1.0.0" (which actually means "1").

Merge pull request #289 from tarcieri/zeroize

Merge pull request #297 from dalek-cryptography/fix-serde 
Fix serde data modeling.

9480844b8d Switch from clear_on_drop to zeroize (fixes #281) 
`zeroize` is WASM-friendly as it has no dependencies on C compilers.

Instead uses Rust's own volatile write semantics and compiler fences to
ensure zeroization is not elided by the compiler.

70e46c9826 Fill in missing Serde impl for MontgomeryPoint. 2019-10-23 15:55:03 -07:00
Henry de Valence
0fc534d989 Use "tuples" instead of "bytes" in the Serde datamodel. 
This is a breaking change to the serialization format.  It fixes it so that the
Serde encoding can match the conventional encoding of each type of object, and
so that Serde can be used with no overhead -- when using serde-bincode, the
Serde encoding now matches the manual encoding.
 2019-10-23 15:40:50 -07:00
Henry de Valence
29ce0d4fe9 Add length checks to serde-bincode tests. 
This ensures that the serde Serialize and Deserialize implementations use
fixed-length Serde tuples, rather than variable-length byte arrays.  This flaw
in data modeling was pointed out by Trevor Perrin.

Merge pull request #293 from dalek-cryptography/remove-build-rs 
Remove build.rs constants generation.
 2019-10-23 14:44:46 -07:00
Henry de Valence
574217694e Remove build.rs. 
This was more useful at the time when we were determining, e.g., optimal lookup
table sizes and could regenerate them more easily, but it came at a massive
complexity cost.  It also meant that we were unable to implement backend
autoselection.  This commit removes the `build.rs` entirely.  In the future, a
different `build.rs` could be added that auto-selects a backend, but it seems
like the current default-u64 setup has been working fine.

Rust fixes for some clippy warnings 
Clippy lints with instances in the project but NOT applied here, since they seem consistently at odds with the projects' style:
- [unreadable literal](https://rust-lang.github.io/rust-clippy/master/#unreadable_literal)
- [cast lossless](https://rust-lang.github.io/rust-clippy/master/#cast_lossless)
- [assign op pattern](https://rust-lang.github.io/rust-clippy/master/#assign_op_pattern)

90baabe50b Ensure Scalar Add and Sub produce canonical results. 
Closes #238.

This issue was discovered independently by both Jack "str4d" Grigg
(issue #238), who noted that reduction was not performed on addition, and
Laurent Grémy & Nicolas Surbayrole of Quarkslab, who noted that it was possible
to cause an overflow and compute incorrect results.

01d9e904e1 Add a missing wrapping_sub in NAF computation. 
Found by @3for; this only affected width-7 NAF computations, which were never
used in the source tree (only width 5, optimal for dynamic cases, and 8, better
for static cases).
