go - Golang https server passing certFile and kyeFile in terms of byte array -

func listenandservetls(addr string, certfile string, keyfile string, handler handler) error 

above function call start https server in golang. works without problem. however, have more deployments, don't want put key files everywhere. thinking let program download key file , cert file centralized place. if there similar function receiving []byte opposed string, easy me that. seems don't see such function in documentations.

looking at source of listenandservetls seems there no option, calls tls.loadx509keypair. that's unfortunate; possibly worth submitting feature request.

in meantime, listenandservetls method not large, , (other tcpkeepalivelistener) not use non-exported it'd simple copy body of method own function , replace load509keypair tls.x509keypair, take []byte of pem encoded data rather filenames. (or perhaps take tls.certificate argument instead.)
