Struct SFrameDecryptor

Source

pub struct SFrameDecryptor { /* private fields */ }

Expand description

Multi-sender SFrame decryptor for one epoch.

Lazily derives per-sender key material from the epoch’s base key as new KIDs are encountered. Maintains an independent replay window per sender.

Obtain via crate::SFrameSession::decryptor.

Implementations§

Source §

impl SFrameDecryptor

Source

pub fn decrypt( &mut self, payload: &[u8], extra_aad: &[u8], ) -> Result<(Vec<u8>, u32), SFrameError>

Decrypts an SFrame payload and returns (plaintext, sender_leaf).

extra_aad must be the same slice passed on the encrypting side.

Source

pub fn reset(&mut self)

Resets all per-sender replay windows (call on epoch change).
