Factory trait for building MessageEncrypter and MessageDecrypter for a TLS1.3 cipher suite.

Required Methods

fn encrypter(&self, key: AeadKey, iv: Iv) -> Box<dyn MessageEncrypter>

Build a MessageEncrypter for the given key/iv.

fn decrypter(&self, key: AeadKey, iv: Iv) -> Box<dyn MessageDecrypter>

Build a MessageDecrypter for the given key/iv.

fn key_len(&self) -> usize

The length of key in bytes required by encrypter() and decrypter().

fn extract_keys( &self, key: AeadKey, iv: Iv, ) -> Result<ConnectionTrafficSecrets, UnsupportedOperationError>

Convert the key material from key/iv, into a ConnectionTrafficSecrets item.

May return UnsupportedOperationError if the AEAD algorithm is not a supported variant of ConnectionTrafficSecrets.

Provided Methods

fn fips(&self) -> bool

Return true if this is backed by a FIPS-approved implementation.
