Jack Grigg edb1941f19 zcash_primitives: Downgrade to `bip0039 0.10` 
`bip0039 0.11` switched from language function arguments to a generic
parameter. We aren't ready to migrate to this yet.

Kris Nuttycombe d6fafa291b Update Sapling note encryption for `zcash_note_encryption 0.3.0` 
Fixes zcash/librustzcash#455
 2023-03-21 11:09:38 -06:00
Kris Nuttycombe c696069f93 Bump zcash_note_encryption to version 0.3.0 for release. 
This removes the path-based dependencies on the `zcash_note_encryption`
crate in favor of using versioned dependencies locally. This better
reflects the future state in which `zcash_note_encryption` is factored
out of the workspace and maintained in a separate repository.

Kris Nuttycombe cb1be45f22 Update CHANGELOGs to reflect the addition of the zcash_primitives/multicore feature. 2023-03-20 15:11:05 -06:00
Kris Nuttycombe 7c1a4c898d Fix wasm32 CI runner. 
The `halo2_proofs/multicore` flag must be disabled when running wasm
builds; this ensures that we do not accidentally include it as a
transitive dependency when building with `--no-default-features`.

Jack Grigg a8003c8ff5 Temporarily re-expose ability to construct invalid Sapling bundles 
Until zcash/zcash#6397 is closed, this ability is needed by `zcashd` for
crossing the FFI.

We re-export them under `sapling::note_encryption` for now to make the
API changes smaller.

Jack Grigg 87d0bd7db1 Refactor `sapling::Note` 
Its internals are now private, and it stores a `PaymentAddress` (and by
extension the diversifier) instead of `g_d`.

Jack Grigg 0a26c812e0 Split `sapling::Authorization::Proof` type into Spend and Output types 
While the Groth16 proofs have identical encodings, they are technically
for different circuits, and we need the ability to differentiate them
during bundle building.

Merge pull request #760 from zcash/759-msrv-1.60 
Bump MSRV for `zcash_primitives` and dependents to 1.60
 2023-01-19 19:33:15 -07:00
Jack Grigg 809427f6bd criterion 0.4 2023-01-20 00:03:10 +00:00
Jack Grigg 49b1cb3e69 Bump MSRV for `zcash_primitives` and dependents to 1.60 
The MSRVs of the component crates are left as-is, partly because our
dependencies don't require us to bump them, and partly because those
crates have no pending changes and are relatively stable. We also plan
to split the component crates out into a separate repository, where it
will be easier to have a separate MSRV.

Closes zcash/librustzcash#759.

Jack Grigg f1d3e03a9b zcash_primitives: Reorganise `sapling` module into submodules 
The module structure now matches the `orchard` crate, to make subsequent
refactoring easier. The public API is not altered by this commit.

Kris Nuttycombe fff6983512 Replace a number of uses of `assert!(matches!(...))` with `assert_matches!(...)` 
The remaining uses of `assert!(matches!(...))` are all in cases where
for some reason the `assert_matches` macro interferes with correct
type inference.
