xfccparser: A parser for Envoy x-forwarded-client-cert

When Envoy terminates TLS, it sends along metadata about the client certificates in an x-forwarded-client-cert HTTP header. This library parses that header into Go structs.

Usage

var req *http.Request

xfccHeader := req.Header.Get(xfccparser.ForwardedClientCertHeader)
clientCerts, err := xfccparser.ParseXFCCHeader(xfccHeader)

Thanks to Alec Thomas for help with the participle representation.
