Enum KeyChange

pub enum KeyChange {
    Handshake {
        keys: Keys,
    },
    OneRtt {
        keys: Keys,
        next: Secrets,
    },
}
Expand description

Key material for use in QUIC packet spaces

QUIC uses 4 different sets of keys (and progressive key updates for long-running connections):

Once the 1-RTT keys have been exchanged, either side may initiate a key update. Progressive update keys can be obtained from the Secrets returned in KeyChange::OneRtt. Note that only packet keys are updated by key updates; header protection keys remain the same.

Variants§
