Add a fiat_u32 backend based on fiat-crypto as well. 
Renames fiat backend directory to fiat_u64 and does the additional plumbing required to make fiat_{u32, u64}_backend equal alternatives.
Adds a few comments.

Implements an Elligator2 map for Curve25519 
This implementation:
- is agnostic on the hash used to pick a field element, even though SHA512 is commonly used,
- follows https://tools.ietf.org/id/draft-irtf-cfrg-hash-to-curve-10.html closely
- tests the outputs of the function using libsignal's implementation.

Remove dev-dependency on deprecated rand_os crate. 
The functionality we were using is now contained in the `rand_core` crate, which
we already depend upon.  As far as testing code goes, only benchmarks still
depend upon `rand`, as they use `thread_rng`.

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 
Switch from `clear_on_drop` to `zeroize` (fixes #281)
 2019-10-23 20:17:14 -07:00
Tony Arcieri
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.
