用于身份验证的chrome app客户端证书

I am trying to find more information/documentation on submitting client certificates using a chrome application (chrome.sockets.tcp). We currently are using chrome sockets and are communicating fine using TLS 1.1. However, we have new requirements that specify using a client certificate for authentication. I am looking for any documentation or examples that will demonstrate the implementation using chrome.sockets.tcp API. Any suggestions are greatly appreciated.I am trying to find more information/documentat
