//! This crate implements the connection part of UKEY2. Depending on context, the name UKEY2 may
//! include only the initial key handshake part (which is the historical origin of the name UKEY2),
//! but may also include the connection encryption part implemented in this crate. In some docs
//! this is also referred to as the "D2D" protocol.
//!
//! The main components in this crate are [`D2DHandshakeContext`] and [`D2DConnectionContextV1`].
//! [`D2DHandshakeContext`] is a wrapper around the `ukey2_rs` crate, controlling the UKEY2 key
//! handshake for the context of the resulting connection. [`D2DConnectionContextV1`] can be created
//! from the handshake context once the handshake is complete, and controls the encryption and
//! decryption of the payload messages.
