How a Tls13CipherSuite generates PacketKeys and HeaderProtectionKeys.

Required Methods

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

Produce a PacketKey encrypter/decrypter for this suite.

suite is the entire suite this Algorithm appeared in. key and iv is the key material to use.

fn header_protection_key(&self, key: AeadKey) -> Box<dyn HeaderProtectionKey>

Produce a HeaderProtectionKey encrypter/decrypter for this suite.

key is the key material, which is aead_key_len() bytes in length.

fn aead_key_len(&self) -> usize

The length in bytes of keys for this Algorithm.

This controls the size of AeadKeys presented to packet_key() and header_protection_key().
