These callback interfaces are designed such that implementations should treatĪll data flowing through them as opaque binary blobs. These will manage loading and storing of identity, prekeys, signed prekeys, Signal_protocol_signed_pre_key_store, and signal_protocol_session_store. Signal_protocol_identity_key_store, signal_protocol_pre_key_store, Building a sessionĪ libsignal-protocol-c client needs to implement four data store callback interfaces: There are also iteration and serialization methods for the above types that shouldīe used as appropriate.
