Struct KeySchedule

struct KeySchedule<const KEY_SIZE: usize> {
    aead: &'static Algorithm,
    key: AeadKey<KEY_SIZE>,
    base_nonce: [u8; 12],
    seq_num: u32,
}

KeySchedule holds the derived AEAD key, base nonce, and seq number common to both a Sealer and Opener.

Fields

aead: &'static Algorithm

key: AeadKey<KEY_SIZE>

base_nonce: [u8; 12]

seq_num: u32
