Enabling SSL Support for CURL in XAMPP

I am using an encoded PHP script, which requires SSL support for CURL.

I am currently using XAMPP for local development and need to know how to update the default CURL such that SSL is enabled over it.

The reason I am looking for an upgrade/support is that I am getting the following error, which when googled up and etc. I understand that SSL is not supported for CURL on my machine.

SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Anyone have any recommendations for me, please? My Current local server config:

XAMPP 1.7.3 cURL support enabled

Not supported on your machine? The error you've posted means that CURL wasn't able to verify the SSL certificate for the remote server, and doesn't necessarily point to a specific inadequacy of your machine. In my previous experience with CURL, it defaults to not accepting/trusting any certificates. Depending on your setup and what you plan to do with it, you may want to trust a single, self-signed certificate [[Cannot verify self-signed certs!]] (e.g. from another machine you run) or you may want to trust a true Certificate Authority (which will enable verification of any certs signed by that CA). This tutorial is fairly straightforward, provided you're familiar with how to change CURL's settings: http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/

You can pick and choose root CAs if you take that path, but if you're just securing transfers between two of your own machines you only need to set CURL to trust the other machine's certificate.

On the other hand, if you indeed have some deeper problem with SSL, it may have resulted from any number of things, such as being built without SSL support. If you are making, configuring, and compiling your own build of CURL, you may want to take a look at http://curl.haxx.se/docs/faq.html on the topics concerning SSL, including

http://curl.haxx.se/docs/sslcerts.html and http://curl.haxx.se/docs/faq.html#What_certificates_do_I_need_when

Take note in the latter link (the FAQ) that self-signed certificates CANNOT be verified. If you're connecting to another of your own servers, its certificate will need to be signed by a CA and the CA's certificate trusted by CURL for the connection to succeed. There are free CAs out there if you only need to get a signature or you can set up your own CA (In my experience, it's just ten times easier to get it signed by someone already set up to do so). If the other server is hosting a secure site that deals with "the real world" (money, products, personal information, etc), its cert should be or you should get it signed by a trusted CA anyway (VISA, Equifax, Comodo, you can find a list of trusted root CAs in every browser).

I've covered what I can in response to that error, but if none of this helps, a little more information on your setup and system might help. :)

A really simple fix that worked for me was to call:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

before calling:

 curl_exec():

in the php file.

I believe that this disables all verification of SSL certificates.

you should sign your public key with a certificate authority (there is some script which can do these things for you ) or you can send your a certification sign request and sign it using your own created CA or some free certificate authority ......

path for the CA.pl script /usr/lib/ssl/misc/CA.pl

this command will create a certificate authority which is reuired to sign your server key the public key of this CA must also be included in the CA_file

$ CA.pl -newca

creates a private key for the server and a certification request

$ CA.pl -newreq

creates the server certificate from the private key and the request (involving the CA private key)

$ CA.pl -sign
