Kris Nuttycombe 544c4ed6bb Remove unused zcash_address dependency. 2022-01-27 16:08:04 -07:00
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.

This also renames a number of legacy key types to better reflect
their intended use.

Kris Nuttycombe ffc4d0cefb Add newtypes for transparent keys at the account & external levels.
This updates UnifiedFullViewingKey to conform to ZIP 316, and
adds types that facilitate this support. These types should likely
be factored out from `zcash_client_backend` into `zcash_primitives`
along with the remainder of the existing unified address support.

Also, factor out sapling internal fvk derivation so that it only
requires (fvk, dk) since we may not have the full extfvk.

Kris Nuttycombe 145d1a57f7 Make transparent signatures commit to all input amounts & scripts.
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.
