EphemeralPublicKey

zebra_chain::sapling::keys

Struct EphemeralPublicKey 

Source 
pub struct EphemeralPublicKey(pub(crate) AffinePoint);
Expand description

An ephemeral public key for Sapling key agreement.

Public keys containing points of small order are not allowed.

It is denoted by epk in the specification. (This type does not represent KA^{Sapling}.Public, which allows any points, including of small order).
