About

Key Encapsulation Mechanisms (KEMs) provide a common API for establishing a symmetric key using public-key cryptography.

This crate implements a KEM-based API for elliptic curve Diffie-Hellman as specified for Hybrid Public Key Encryption (HPKE) which is described in RFC9180.

⚠️ Security Warning

The implementation contained in this crate has never been independently audited!
