The certificate byte stream is available in the Raw field of the Certificate struct.
You can for example output received certificates PEM encoded like this: for _, c := range r.TLS.PeerCertificates { pem.Encode(os.Stdout, &pem.Block{Type: "CERTIFICATE", Bytes: c.Raw}) } Or you can just save c.Raw in a file if you prefer binary format. See https://gist.github.com/snabb/01c71af8cc9815e2fed68767bbb445af for complete example.
