OCSPResponse event is not fired with tls.connect when requestOCSP is set

[dingjiedanielyang-sec]

Hi folks,

Need some help to I am attempting to get the OCSPResponse to check whether a certification is revoked or not by using the following code, but the OCSPResponse event is never triggered with the following codes.

const tls = require('tls'),
    PORT = 443,
    HOST = 'google.com'

const options = {
    rejectUnauthorized: true,
    secureProtocol: 'TLSv1_2_method',
    servername: HOST,
    secure: true,
   // enableTrace: true,
    requestOCSP: true,
};

const client = tls.connect(PORT, HOST, options, function () {
    if (client.authorized) {
        console.log("Connection authorized by a Certificate Authority.");
    } 
    let certificate = client.getPeerCertificate(true);
    console.log("---------------")
    client.on("OCSPResponse", function(data) {
        console.log(data.toString())
    });
    client.on("data", function (data) {
        console.log('Received: %s',data.toString().replace(/(\n)/gm, ""));
    });
    client.end(() => {
        console.log("Client closed successfully");
    });
});

Servers can (and many do) ignore OSCP status requests; they're an optional part of the protocol. google.com seems to be one:

$ curl --cert-status https://google.com
curl: (91) No OCSP response received
