Required Methods

fn generate_ephemeral_keypair(&self) -> Result<Box<dyn LocalKeyPair>>

Generate a random ephemeral local key pair.

fn import_key_pair( &self, components: &EcKeyComponents, ) -> Result<Box<dyn LocalKeyPair>>

Import a local keypair from its raw components.

fn import_public_key(&self, raw: &[u8]) -> Result<Box<dyn RemotePublicKey>>

Import the public key component in the binary uncompressed point representation.

fn compute_ecdh_secret( &self, remote: &dyn RemotePublicKey, local: &dyn LocalKeyPair, ) -> Result<Vec<u8>>

fn hkdf_sha256( &self, salt: &[u8], secret: &[u8], info: &[u8], len: usize, ) -> Result<Vec<u8>>

fn aes_gcm_128_encrypt( &self, key: &[u8], iv: &[u8], data: &[u8], ) -> Result<Vec<u8>>

Should return [ciphertext, auth_tag].

fn aes_gcm_128_decrypt( &self, key: &[u8], iv: &[u8], ciphertext_and_tag: &[u8], ) -> Result<Vec<u8>>

fn random_bytes(&self, dest: &mut [u8]) -> Result<()>
