Trying to get PHP streams working with Thawte TLS RSA CA G1 - internal error

Question

I try to get PHP accepting the a certificate which Chrome accepts.

I created the following minimal reproducing example:

echo OPENSSL_VERSION_TEXT;

require 'vendor/autoload.php';
    $fetch = new \ParagonIE\Certainty\RemoteFetch('/tmp/');
    $latestBundle = $fetch->getLatestBundle();

    $context = stream_context_create(
        [
            'ssl' => array(
                'cafile' => $latestBundle->getFilePath(),
                'SNI_enabled' => true,
            )
        ]
    );

$url = 'https://example.com:8080/x/y';

    echo file_get_contents($url  . '?wsdl', false, $context);

I am using https://github.com/paragonie/certainty to get the latest CAcerts.

I get the following error

OpenSSL 1.0.2g  1 Mar 2016
PHP Warning:  file_get_contents(): 
SSL operation failed with code 1. OpenSSL Error messages:
error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert 
internal error in /tmp/test/test.php on line 20
PHP Warning:  file_get_contents(): Failed to enable crypto in 
/tmp/test/test.php on line 20
PHP Warning:  file_get_contents(https://example.com:8080/x/y? 
wsdl): failed to open stream: operation failed in 
/tmp/test/test.php on line 20

What is going wrong here?

Unfortunately I cannot share the URL (it's behind a Firewall anyways).

Accessing it with curl --insecure works - but I would really like to properly verify the CA cert

EDIT SSLyze outputs this:

Answer 1

The internal error is resolved like this:

    $context = stream_context_create(
        [
            'ssl' => array(
                    'cafile' => $latestBundle->getFilePath(),
                    'SNI_enabled' => true,
                    'ciphers' => 'HIGH:TLSv1.2:TLSv1.1:TLSv1.0:SSLv3:SSLv2',
                    'verify_peer' => false,
                    'verify_peer_name' => false,
                    'crypto_disable_compression' => true,
                    'method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT,
                    'verify_depth' => 10,
            )
        ]
    );

But still I cannot verify the CA cert.

In Chrome it works fine.

This is because Chrome does some workarounds, see https://security.stackexchange.com/questions/199963/certificate-works-in-chrome-firefox-but-not-with-curl-unable-to-get-local-is

So I have to wait until the chain is configured properly.
