Jack Grigg 418cba0e85 group: Document that Group::random is non-deterministic 2020-08-12 08:18:45 +01:00
Jack Grigg ed6b7eceef group: Hard-code a w-NAF window size of 4 
We were already ignoring the actual bit length of the scalar, and
selecting the window size based on the maximum bit length, which
effectively hard-coded a window size of 4.

Jack Grigg 1e8fd4da68 group: CofactorGroup::mul_by_cofactor -> CofactorGroup::clear_cofactor 
The generic API now only guarantees that the torsion component is
cleared deterministically; group elements may be multiplied by multiples
of the cofactor (not necessarily the actual cofactor), as long as the
choice of multiplier is fixed for a given implementation.

bellman: add VerificationError (#254) 
* bellman: add VerificationError

This adds a distinct VerificationError type to the crate and changes
`verify_proof` to return `Result<(), VerificationError>` rather than
`Result<bool, SynthesisError>`.  This is significantly safer, because it avoids
the need to mix pattern-matching logic with boolean logic (the cause of
RUSTSEC-2019-0004).

* Rename VerificationError variants per review comments.

* Add missing Clone impl to VerificationError.

Jack Grigg c921cfcf97 zcash_proofs: Add LocalProver::bundled 
Requires the bundled-prover feature, which enables the
wagyu-zcash-parameters crate and adds around 50 MiB to the overall
binary size. That crate bundles the same Sapling parameter files we
normally obtain from disk, so we constrain them to match the same
hard-coded hashes.
