Merge pull request #417 from nuttycom/incremental_merkle_tree_ser 
Add manual serialization for bridgetree::Frontier
 2021-08-17 14:57:59 +01:00
Jack Grigg 4b4dd2ea55 zcash_note_encryption: Add support for batch-parsing `ephemeral_key` 
This is useful when the underlying curve requires an inversion to parse
an encoded point (such as for Jubjub).

Jack Grigg 0f15743200 Disable default benchmark harness for all workspace crates 
This is necessary in order to provide criterion-specific arguments to
`cargo bench`, such as `--profile-time`.

Kris Nuttycombe 2945905d52 Implement manual serialization for incremental Merkle tree components. 
This also adds parsing of the legacy CommitmentTree format,
to permit easy migration of persisted data.

Jack Grigg 8527dcbc32 zcash_address: Remove outdated unified::Receiver documentation 
Receiver ordering is now explicitly defined by Typecode, and Receiver
is now a public type.

Jack Grigg 060a15eaf8 zcash_address: Enable constructing a unified::Address from Vec<Receiver> 
This enforces the same structural validity checks as at parsing time.
 2021-07-12 13:39:01 +01:00
Jack Grigg 384af079a8 zcash_address: Add `unified::Address::receivers{_as_parsed}` APIs 
These expose the receivers in sorted order, and in parsed order.

Jack Grigg c7c79d266e zcash_note_encryption: Add `ShieldedOutput::ephemeral_key() -> EphemeralKeyBytes` 
This replaces the `ShieldedOutput::epk() -> &Domain::EphemeralPublicKey`
which could not be satisfied by output types that did not parse epk.

Jack Grigg 1222391dd7 Migrate to bitvec 0.22, ff 0.10, etc. 
Requires patching three dependencies:

- bellman is pending a new release.
- nom is part of the funty breakage; we are blocking on a new release.
- orchard is in development.

Jack Grigg eba6f417fe zcash_note_encryption: Doc fixes 2021-05-29 00:15:25 +01:00
Jack Grigg 362838c3fa zcash_note_encryption: Fix array size in Domain::extract_{esk, pk_d} 
Decrypted output size is `OUT_PLAINTEXT_BYTES`, which the decryptor
can always provide (either by decrypting into the correct size array
as now, or truncating the buffer before passing it to the domain).

Jack Grigg f6705f23c3 zcash_note_encryption: Add ovk recovery API 2021-05-28 23:45:23 +01:00
Jack Grigg ae43e6c074 zcash_note_encryption: Pass cmstar_bytes to Domain::derive_ock 
PRF^ock in the spec takes cm* as a byte array.
 2021-05-28 23:41:13 +01:00
Jack Grigg ee2b96c82d zcash_note_encryption: s/TryFrom/From on ExtractedCommitmentBytes bound 
This was left over from an earlier refactor where we could call a domain
API to extract cmstar from a note commitment (which could fail for
Orchard). This part of extraction was subsequently refactored into the
domain logic (and is rejected earlier for Orchard). The resulting bound
is wrong because it's always possible to serialize a scalar.

Jack Grigg 16627b4569 zcash_note_encryption: Enforce ZIP 212 check on esk from outPlaintext 
It needs to equal the esk derived from the note (for v2 note plaintexts).

Jack Grigg ff94f66d8e zcash_address: Fix padding and F4Jumble positions in Address::to_bytes 
These need to be applied to the entire UA encoding, not to the encoding
of each individual receiver.

Jack Grigg ae2b8bfd6d zcash_address: Replace Orchard address encodings with Unified Addresses 
This commit removes the now-undefined Orchard encoding logic, and adds
the general Bech32m encoding/decoding logic for Unified Addresses. The
internal data format of Unified Addresses is not correct in this commit.
