Expand description

Interface for storing signed Kyber pre-keys downloaded from a server.

NB: libsignal makes no distinction between one-time and last-resort pre-keys.

Required Methods§

Source

fn get_kyber_pre_key<'life0, 'async_trait>( &'life0 self, kyber_prekey_id: KyberPreKeyId, ) -> Pin<Box<dyn Future<Output = Result<KyberPreKeyRecord>> + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Look up the signed kyber pre-key corresponding to kyber_prekey_id.

Source

fn save_kyber_pre_key<'life0, 'life1, 'async_trait>( &'life0 mut self, kyber_prekey_id: KyberPreKeyId, record: &'life1 KyberPreKeyRecord, ) -> Pin<Box<dyn Future<Output = Result<()>> + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Set the entry for kyber_prekey_id to the value of record.

Source

fn mark_kyber_pre_key_used<'life0, 'life1, 'async_trait>( &'life0 mut self, kyber_prekey_id: KyberPreKeyId, ec_prekey_id: SignedPreKeyId, base_key: &'life1 PublicKey, ) -> Pin<Box<dyn Future<Output = Result<()>> + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Mark the entry for kyber_prekey_id as “used”.

A one-time Kyber pre-key should be deleted after this point. A last-resort pre-key should not immediately be deleted, but should check whether the same combination of pre-keys was used with the given base key before, and produce an error if so.
