Verification of SSL Issuer "thawte SSL CA - G2" fails on Debian 8 #11

This issue is not really related to Klarna/PHP-XMLRPC but I guess it's good to know:

This curl exception will be thrown: CURL error: SSL certificate problem: unable to get local issuer certificate when doing request as following:

There seems to be no way to register a CA Root Certificate on the fly for requests against Klarna API. You need to set curl.cainfo for cURL in php.ini globally to resolve this issue since Klarna/XMLRPC/Klarna isolates its instance of PhpXmlRpc\Client completely.

I have this issue as well currently. How did you solve it?

razorness commented 8 years ago

The only way is to deactivate SSL and hope that the deb package maintainer will release a fixed version. :(

gildebrand commented 8 years ago

I've ben trying to find a way to deactivate it but could not find a working solution. Would you mind pointing me in the right direction?

razorness commented 8 years ago

Here is my code. The good news: I still use SSL. But I had to deactivate the chain of trust.

$klarna = new Klarna();
$klarna->config(
    'id',
    'secret',
    'Country',
    'Language',
    'Currency',
    Klarna::BETA,
    // added this option in my fork to handle UTF-8 correctly
    ini_get('default_charset')   
);

/*
 * Hackish way to deactivate Peer Verification for SSL
 */
$reflClass = new \ReflectionClass($klarna);
$reflProperty = $reflClass->getProperty('xmlrpc');
$reflProperty->setAccessible(true);
/** @var Client $xmlrpc */
$xmlrpc = $reflProperty->getValue($klarna);
$xmlrpc->setSSLVerifyPeer(false);
$reflProperty->setAccessible(false);

For the general problem, take also a look at: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774882#34

That works great as a workaround. Thank you very much! 😄

BTW, this affects Ubuntu (14.04) as well.
