Trait Implementations

impl Tls12AeadAlgorithm for GcmAlgorithm

fn decrypter( &self, dec_key: AeadKey, dec_iv: &[u8], ) -> Box<dyn MessageDecrypter>

Build a MessageDecrypter for the given key/iv.

fn encrypter( &self, enc_key: AeadKey, write_iv: &[u8], explicit: &[u8], ) -> Box<dyn MessageEncrypter>

Build a MessageEncrypter for the given key/iv and extra key block (which can be used for improving explicit nonce size security, if needed).

fn key_block_shape(&self) -> KeyBlockShape

Return a KeyBlockShape that defines how large the key_block is and how it is split up prior to calling encrypter(), decrypter() and/or extract_keys().

fn extract_keys( &self, key: AeadKey, write_iv: &[u8], explicit: &[u8], ) -> Result<ConnectionTrafficSecrets, UnsupportedOperationError>

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

fn fips(&self) -> bool

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