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.	2019-07-10 13:53:22 -04:00

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.	2019-06-06 13:38:33 +01:00
