Struct SessionCrypto 

pub struct SessionCrypto { /* private fields */ }

Session crypto for ONE connection endpoint: seals in the endpoint’s send direction, opens in the peer’s.

Implementations

impl SessionCrypto

pub fn client(c2s: [u8; 32], s2c: [u8; 32]) -> Self

Client endpoint (sends c2s, receives s2c).

pub fn server(c2s: [u8; 32], s2c: [u8; 32]) -> Self

Server endpoint (sends s2c, receives c2s).

pub fn seal(&mut self, plaintext: &[u8]) -> TransportResult<Vec<u8>>

Seal one frame: counter nonce + AAD binding direction/protocol/ counter (WBS-509/510).

pub fn open(&mut self, frame: &[u8]) -> TransportResult<Vec<u8>>

Open one frame: enforces the strictly-increasing counter (replay, WBS-511) and the AAD binding to OUR receive direction (reflection, WBS-510) before returning the plaintext.
