//! An experimental
//! [OSCORE](https://tools.ietf.org/html/rfc8613)
//! implementation with
//! [EDHOC](https://datatracker.ietf.org/doc/draft-ietf-lake-edhoc)
//! key exchange, intended for embedded devices.
//!
//! The EDHOC implementation is based on the older
//! [version 14](https://tools.ietf.org/html/draft-selander-ace-cose-ecdhe-14)
//! of draft-selander-ace-cose-ecdhe. It only does authentication with raw
//! public keys (RPK), so it covers the asymmetric authentication scenario, but
//! not the symmetric one using pre-shared keys (PSK). On the OSCORE side, it
//! does key derivation using the master secret and master salt, which can be
//! established with EDHOC.
//!
//! There is [documentation](https://martindisch.github.io/oscore/oscore/) as
//! well as a [demo implementation](https://github.com/martindisch/oscore-demo)
//! using this library, with a resource server on an STM32F3, a client on an
//! STM32F4 and a CoAP proxy running on a Raspberry Pi.
//!
//! ## Security
//! This should **not currently be used in production code**, use at your own
//! risk.
