Jack Grigg 79006ecbdf Unify Sapling tree depth constants 
When sapling-crypto is refactored, the zcash_primitives::sapling
constant would become the canonical one.

Jack Grigg e67560b154 Document merkle_tree module 2019-07-10 13:53:22 -04:00
Jack Grigg b9cea33804 Move merkle_tree::Node into sapling module 
This makes the merkle_tree module properly generic over the tree hash.
It still hard-codes a depth 32 tree, because Rust doesn't yet support
generic sizes, and we are unlikely to need to alter the tree depth in
future circuit changes.

Jack Grigg d1ce6749fe Bump minimum Rust version to 1.36 2019-07-10 13:12:26 -04:00
Jack Grigg 999dcbfcab Migrate to blake2b_simd and blake2s_simd crates 
The primary reason for migrating is that these crates provide APIs for
setting the personalisation string. This enables us to depend solely on
published crates, and thus publish our own crates.

The SIMD implementations are ported from libsodium.

Closes #67.

Jack Grigg 060977fe54 Return edwards::Point from sapling_ka_agree 
This matches how sapling_ka_agree and kdf_sapling are defined in the
protocol spec. kdf_sapling also now takes ownership of dhsecret to
discourage use of the sapling_ka_agree output elsewhere.

Jack Grigg 34658c4bd3 Raise minimum Rust version to 1.32 
The crypto_api_chachapoly uses two new features introduced in 1.32:

- Self struct constructors
- u64::to_le_bytes()
 2019-04-11 06:41:22 -07:00
Jack Grigg 6dcb4040af Switch to crypto_api_chachapoly crate 
This crate exposes both the ChaCha20Poly1305 IETF construction, and the
underlying ChaCha20 IETF primitive, removing the need for depending on
our own fork of the previous chacha20-poly1305-aead crate.
