zcash_note_encryption
This crate implements the in-band secret distribution scheme for the Sapling and Orchard protocols. It provides reusable methods that implement common note encryption and trial decryption logic, and enforce protocol-agnostic verification requirements.
Protocol-specific logic is handled via the Domain trait. Implementations of this
trait are provided in the zcash_primitives (for Sapling) and orchard crates;
users with their own existing types can similarly implement the trait themselves.
