Description

According to RFC 6455, a WebSocket client's handshake is just an HTTP Upgrade request. The client's handshake request should contain the Sec-WebSocket-Key header field containing a randomly generated 16-byte value. To accept the handhsake, the server generates a Sec-WebSocket-Accept header field basing on the received Sec-WebSocket-Key value. Use this method to generate the value of the Sec-WebSocket-Accept field of the server's handshake response.
