Deirdre Connolly b7bd642910 Clippy pass 2020-04-18 04:40:31 -04:00
Deirdre Connolly bc13bccb8d Add a bunch of stuff for JubJub GroupHash, FindGroupHash, etc 
Until it can be imported into the jubjub crate and upstreamed.
It has been ported from the types used in zcash_primitives and cleaned up
but still needs testing.

Deirdre Connolly 7e2ae70d66 Wrap AuthorizingKey around redjubjub::PublicKey<SpendAuth>

Deirdre Connolly b9deef2956 Break out crh_ivk() and invoke in IncomingViewingKey derivation 
There is only one invocation of this PRF but it's nice to keep it consistent with
the PRF^expand ones we have too.

Deirdre Connolly 2e063998fb Add a new() and impl From<[u8; 32]> for SpendingKey 
Currently fills/receives 32 random bytes and forces the top 4 bits to
zero, ala clamping. If there is a nicer way to csprng'ly fill 252 bits
without clamping, that would be nicer, less bias.

Deirdre Connolly f84a8c682a Derive PayingKey's from SpendingKey's 
And test that we can still derive TransmissionKey's from PayingKey's,
as they are aliases for x25519_dalek PublicKey/StaticSecret types that already
impl From<_> for each other.

Deirdre Connolly ee32de2b86 Derive Sprout ReceivingKey's from SpendingKey's via SHA256Compress
