Trait for key encapsulation mechanisms

Required Methods

fn generate_keypair(&self) -> Result<KemKeypair>

Generate a keypair

fn encapsulate(&self, public_key: &KemPublicKey) -> Result<(Vec<u8>, Vec<u8>)>

Encapsulate a shared secret

fn decapsulate( &self, secret_key: &KemSecretKey, ciphertext: &[u8], ) -> Result<Vec<u8>>

Decapsulate a shared secret

fn derive_public_key(&self, secret_key: &KemSecretKey) -> Result<KemPublicKey>

Derive public key from secret key

fn auth_encapsulate( &self, sender_sk: &KemSecretKey, recipient_pk: &KemPublicKey, ) -> Result<(Vec<u8>, Vec<u8>)>

Authenticated encapsulation (RFC 9180 AuthEncap)

fn auth_decapsulate( &self, recipient_sk: &KemSecretKey, ciphertext: &[u8], sender_pk: &KemPublicKey, ) -> Result<Vec<u8>>

Authenticated decapsulation (RFC 9180 AuthDecap)

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
