Method Detail

• loadKyberPreKey

   KyberPreKeyRecord loadKyberPreKey(int kyberPreKeyId)

  Load a local KyberPreKeyRecord.

  Parameters:

  kyberPreKeyId - the ID of the local KyberPreKeyRecord.

  Returns:

  the corresponding KyberPreKeyRecord.

• loadKyberPreKeys

   List<KyberPreKeyRecord> loadKyberPreKeys()

  Load all local KyberPreKeyRecords.

  Returns:

  All stored KyberPreKeyRecords.

• storeKyberPreKey

   void storeKyberPreKey(int kyberPreKeyId, KyberPreKeyRecord record)

  Store a local KyberPreKeyRecord.

  Parameters:

  kyberPreKeyId - the ID of the KyberPreKeyRecord to store.

  record - the KyberPreKeyRecord.

• containsKyberPreKey

   boolean containsKyberPreKey(int kyberPreKeyId)

  Parameters:

  kyberPreKeyId - A KyberPreKeyRecord ID.

  Returns:

  true if the store has a record for the kyberPreKeyId, otherwise false.

• markKyberPreKeyUsed

   void markKyberPreKeyUsed(int kyberPreKeyId, int signedPreKeyId, ECPublicKey baseKey)

  Mark a KyberPreKeyRecord in the local storage as used.

  If it's a one-time pre-key, remove it.

  If it's a last-resort pre-key, check whether this specific (kyberPreKeyId, signedPreKeyId, baseKey) tuple has been seen before, and throw an exception if so. If not, record it for later. Entries can be removed when either the Kyber key or the last-resort key is deleted (not just rotated).

  Parameters:

  kyberPreKeyId - The ID of the KyberPreKeyRecord to be marked.

  signedPreKeyId - The ID of the SignedPreKeyRecord that was used with this Kyber pre-key.

  baseKey - The session-specific key from the sender used with this Kyber pre-key.
