//! User-facing TLS and DTLS protocol surface for the NoxTLS Rust port.
//!
//! This crate wires together a modeled `protocol` handshake and record layer, deterministic key-share
//! helpers for interop, optional PSK ticket persistence, and re-exports `noxtls_io::transport` adapters
//! for blocking, async, and embedded I/O profiles.
