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.

2b51978553 Remove nightly recommendation now that subtle has stable opt barriers. 
This bumps the required `subtle` version to `2.2.1`, which contains those changes.

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.
