Current stable version is __0.4.2-SNAPSHOT__. The full-dpulex RPC over websock is ok, the security level is still disabled until the protocol part will be sabilized.
This is a connection-agnostic, kotlin multiplaftorm library providing full-duplex RPC type binary protocol, effective to work with binary data, such as encrypted data, keys, multimedia, etc. Default implementation uses websockets transport (binary frames) available on all supported platofrms (currently, JS and JVM).
