mpc-websocket-0.2.1 has been yanked.
Websocket server for MPC key generation and signing using JSON-RPC.
The library has been designed so that the messages transferred between parties are only stored in memory for the shortest lifetime; that is just enough time to extract the required routing information to be able to handle the message.
Auditors will want to pay particular attention to the handling of the SESSION_MESSAGE and NOTIFY_PROPOSAL methods which are sensitive for security and privacy reasons.
By looking at the source for Group, Session and State structs auditors can verify that no sensitive information is stored in the server state.
