pub struct Envelope<S> { /* private fields */ }

AEAD envelope. State parameter distinguishes sealed-for-transport from opened-for-use. Never deriving Clone / Copy — a sealed envelope is single-use (counter is one-shot).

Implementations

impl<S> Envelope<S>

pub fn counter(&self) -> u32

pub fn session_id(&self) -> &str

Session id this envelope’s AAD is bound to.

pub fn path(&self) -> &str

Request path this envelope’s AAD is bound to.

impl Envelope<Sealed>

pub fn ciphertext(&self) -> &[u8]

Raw ciphertext || tag (16 bytes of Poly1305 tag at the end).

pub fn nonce(&self) -> &[u8; 12]

Nonce this envelope was sealed under.

impl Envelope<Open>

pub fn plaintext(&self) -> &[u8]
