Key Schedule

This module defines types and implementations for key schedule operations. It provides the EpochAuthenticator and ResumptionPskSecret types.

Internal Documentation

The key schedule is described in Section 8 of the MLS specification. It evolves in epochs, with new key material injected in each epoch.

The key schedule flow (from Section 8 of the MLS specification) is as follows:

Re-exports

pub use psk::ExternalPsk;

pub use psk::PreSharedKeyId;

pub use psk::Psk;
