Fields

sending_key: [u8; 32]

Key for sending

receiving_key: [u8; 32]

Implementations

impl SessionKeys

pub fn new(sending_key: [u8; 32], receiving_key: [u8; 32], now: u64) -> Self

Create new session keys

pub fn needs_rekey(&self, now: u64) -> bool

Check if keys need rotation

pub fn next_nonce(&self) -> Result<u64, WireGuardError>

Get and increment the sending nonce
