Kris Nuttycombe c4da498cf4 Shield funds to the internal Sapling key for a specified account.
This updates `shield_transparent_funds` to look up the internal
(change) address for the account specified, and use that as the
destination for shielding transparent funds.

Fixed #614

Kris Nuttycombe 6156215d4c Add parallelized batched trial decryption to wallet scanning.

Kris Nuttycombe cdfaa57496 Add migrations to support using UFVKs instead of Sapling extfvks.
Fixes #594
2022-08-18 10:15:58 -06:00
Kris Nuttycombe f1c2da7b1d Add sapling::NullifierDerivingKey newtype.
Nullifier computation only requires the nullifier deriving key,
not the entire Sapling viewing key. This separation of concerns
will be needed for batch decryption when wallet-internal keys
will need to be considered.

Kris Nuttycombe 5873950648 Restructure batch decryption to avoid cartesian product of results.
While it is necessary in the worst case to perform `m * n` decryptions,
where `m` is the number of outputs being decrypted and `n` is the number
of IVKs, it is possible to stop performing trial decryptions when the
first successful decryption is performed. Also, it's inconvenient and
unnecessary to return the full cartesian product of these results, as
only one IVK will decrypt a given output. This commit modifies batch
trial decryption to stop on the first successful decryption, and instead
of returning the cartesian product of results we return the index of the
input IVK along with the output it decrypted. Note that this means that
trial decryption is not constant-time with respect to the number and/or
order of IVKs.

Jack Grigg 76d015ed11 zcash_client_backend: Fix `UnifiedFullViewingKey` Sapling item type
Per ZIP 316, the Sapling FVK Encoding only includes `(ak, nk, ovk, dk)`
which is a subset of the Sapling `ExtendedFullViewingKey`. We therefore
need to use `DiversifiableFullViewingKey` inside `UnifiedFullViewingKey`
in order to make it parseable from the UFVK string encoding.

`zcash_client_sqlite::wallet::get_extended_full_viewing_keys` has been
removed as a consequence of this change: we can no longer reconstruct
the correct `ExtendedFullViewingKey` from the `UnifiedFullViewingKey`.

Kris Nuttycombe 71657b4f18 Generalize vector and array writes & reads.
In a number of places, we transform other kinds of collections with
known length information into vectors simply to be able to use them with
`Vector::write` or `Vector::read`. We can avoid these extra allocations
by writing from iterators directly, and similarly by reading directly
into our desired collection types.

Kris Nuttycombe a1e693d15f Remove the Wif type; it should not be used.
We should attempt to avoid passing spending keys back and forth
across the FFI entirely, but in any case this is no longer the
correct type to use at this boundary; we should use the encoding
of the transparent component of a unified spending key instead.

Transparent UTXOs are referred as pair of previous txid and index. In
order to verify UTXO's amount in HWW (hardware wallet), whole previous
transaction containing this UTXO must be streamed into the device. This
increases complexity of signing process significantly.

zcash/zips#574 identifies this problem and suggests a modification
to ZIP-244 to resolve this issue, by adding three new fields to
section S.2 of the signature hash.

Sapling address generation depends only on an FVK and

keys, we need to break the dependence upon Sapling extended
full viewing keys, so this makes the address generation
methods of SaplingExtendedFullViewingKey usable without
coupling them to the ability to derive child full viewing keys.

Kris Nuttycombe 1373221439 Renames the `ExtendedFullViewingKey::address` method to `find_address`.
This also adds a new semantically different `address` method which
attempts to produce an address given the specified diversifier index,
and returns `None` if that index does not produce a valid diversifier.

It is then up to the caller to search the diversifier index space if
the diversifier index that they are attempting to use does not result in
a valid diversifier.

Jack Grigg 83c6a2d1ca Store OutputDescription `ephemeral_key` as bytes
This removes an unnecessary `to_bytes` during trial decryption of notes,
and more closely matches the protocol spec. We retain the consensus rule
canonicity check on epk due to `SaplingVerificationContext::check_output`
taking a `jubjub::ExtendedPoint`, forcing `zcashd` to parse the bytes.

Jack Grigg 8a84203685 Remove Default impl from MemoBytes
Memo fields have two ways to encode an empty memo:

- 0xF6 followed by all-zeroes, encoding "there is no memo".
- All-zeroes, encoding the empty UTF-8 string.

In almost all cases you want the former, but users thinking about byte
slices may expect MemoBytes::default() to result in the latter. To
ensure clarity, we now require calling either MemoBytes::default() or
MemoBytes::from_bytes(&[]) to be explicit.

No such confusion exists for the Memo enum, because the two types are
visibly separated as different enum cases, and Memo::Empty makes sense
as the default.

Jack Grigg c7a3ef0e88 Split memo-handling into MemoBytes struct and Memo enum
The MemoBytes struct is a minimal wrapper around the memo bytes, and only
imposes the existence of null-padding for shorter memos. The only error
case is attempting to construct a memo that is too long. MemoBytes is
guaranteed to be round-trip encodable (modulo null padding).

The Memo enum implements the additional memo rules defined in ZIP 302,
interpreting the contents of a memo (for example, parsing it as text).

Simplify a few pattern matches
A few pattern-matches correspond directly to standard combinators on
`Result`, `Option`. This uses them for concision / clarity.
