The document function returns a JSON object containing the ID and encryption key assigned to the uploaded document. Once received by the server, uploaded documents are immediately encrypted using a uniquely generated encryption key. This key is not persistently stored on the server. Therefore, it must be stored by the client and sent back to the server with every subsequent request that refers to this particular document.
