# 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.
