# Rosenpass internal libsodium bindings
|
||||
|
||||
Rosenpass internal library providing traits for cryptographic primitives.
|

//! Traits and implementations for Key Encapsulation Mechanisms (KEMs)

//! KEMs are the interface provided by almost all post-quantum

//! secure key exchange mechanisms.
|
||||
//!
|

//! Conceptually KEMs are akin to public-key encryption, but instead of encrypting
|

//! arbitrary data, KEMs are limited to the transmission of keys, randomly chosen during
|
||||
//!
|

//! encapsulation.
|
||||
//! The [KEM] Trait describes the basic API offered by a Key Encapsulation
|
||||
//! Mechanism. Two implementations for it are provided, [StaticKEM] and [EphemeralKEM].
