Jack Grigg 76a39d29c1 Change diversify_hash and ka_orchard to use non-zero types 
This matches the changes to KA^Orchard in spec version 2021.1.23.
 2021-05-11 18:51:57 +08:00
Jack Grigg 9a828febd7 Change `commit_ivk` to return a non-zero Pallas base field element 
The type system now enforces that `ivk != 0`.

Jack Grigg 497f7e0b86 Remove bundle::Unauthorized type 
It is being replaced by context-specific unauthorized or
partially-authorized types. The only general type we need is Authorized
which is used in transactions.

Jack Grigg a60051c8a2 Add from_raw constructors to NoteValue and ValueSum 
These might be replaced later with APIs that can provide more useful
bounds checks, but we do need some way to construct these types.
 2021-04-27 12:27:23 +12:00
Jack Grigg 52d87e257c Return SpendingKey from Note::dummy 
We need the spending keys to create valid spendAuth signatures for
Actions containing dummy spent notes.
 2021-04-27 12:26:24 +12:00
Jack Grigg 5ec65c5d2a Add a mutable context to Bundle::{try_}authorize 
This enables us to work around lifetime restrictions on e.g. the
randomness source at signing time, where it is needed for both
per-Action and Bundle-level signatures.
