rings_node::prelude::message::e2e

Struct E2eStreamDecryptor 

Source 
pub struct E2eStreamDecryptor { /* private fields */ }
Expand description

Stateful streaming decryptor for direct ElGamal body frames.

Implementations§

Source§

impl E2eStreamDecryptor

Source

pub fn new( stream_id: Uuid, expected_sender: Did, recipient_secret_key: SecretKey, ) -> E2eStreamDecryptor

Create a direct ElGamal streaming decryptor for a recipient secret key.

Source

pub fn with_reorder_window( stream_id: Uuid, expected_sender: Did, recipient_secret_key: SecretKey, reorder_window: u64, ) -> E2eStreamDecryptor

Create a decryptor with an explicit future-frame reorder window.

Source

pub fn decrypt_next(&mut self, frame: &E2eStreamFrame) -> Result<Vec<u8>, Error>

Decrypt one frame and return newly contiguous plaintext bytes.

Out-of-order future frames are buffered and return an empty vector until the missing lower sequence numbers arrive.

Source

pub fn finish(&self) -> Result<(), Error>

Verify that the stream ended with an authenticated final frame.
