Starting a server with
encrypt against a datastore that was not encrypted may result in failures when it comes to decrypt a message, which may not happen immediately upon startup. Instead, it will happen when attempting to deliver messages to consumers. However, when possible, the server will detect if the data was not encrypted and return the data without attempting to decrypt it. The server will also detect which cipher was used to encrypt the data and use the proper cipher to decrypt, even if this is not the currently selected cipher.
