Struct E2eStreamEncryptor 

pub struct E2eStreamEncryptor { /* private fields */ }

Stateful streaming encryptor for direct ElGamal body frames.

Implementations

impl E2eStreamEncryptor

pub fn new( stream_id: E2eStreamId, sender_public_key: PublicKey<33>, recipient_public_key: PublicKey<33>, ) -> Result<Self>

Create a direct ElGamal streaming encryptor for recipient_public_key.

pub fn encrypt_next( &mut self, plaintext: &[u8], rng: &mut impl RngCore, ) -> Result<E2eStreamFrame>

Encrypt one non-final plaintext frame.

pub fn encrypt_next_with_default_rng( &mut self, plaintext: &[u8], ) -> Result<E2eStreamFrame>

Encrypt one non-final plaintext frame with the default thread-local RNG.

pub fn encrypt_final( &mut self, plaintext: &[u8], rng: &mut impl RngCore, ) -> Result<E2eStreamFrame>

Encrypt the final plaintext frame and close this stream.

pub fn encrypt_final_with_default_rng( &mut self, plaintext: &[u8], ) -> Result<E2eStreamFrame>

Encrypt the final plaintext frame with the default thread-local RNG.
