cURL says certificate is expired, Firefox disagrees
Solution 1
Your cert bundle is probably out of date.
You can get one that's maintained by the curl developers at http://curl.haxx.se/ca/cacert.pem
To use it:
<?
$ch = curl_init("http://example.com");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, '/path/to/cacert.pem');
$response = curl_exec($ch);
Solution 2
My curl is using the certificate bundle stored in:
/etc/ssl/certs/ca-certificates.crt
I've had this problem in the past, and I fixed it by looking at a machine where curl was working and comparing the .crt files from those two machines, and copying the missing certificate over.
I just had this problem again, and I fixed it this time by just copying the entire file over from the newer machine (a more recent Ubuntu install----the machine where I have the problem is ancient).
And it worked.

I'm trying to access an internal site via cURL (which I could access several days ago). However, cURL gives the error
curl: (60) SSL certificate problem: certificate has expired
. If I useopenssl
to check the start and end dates of the certificate, it gives a timeframe that I'm well within:echo | openssl s_client -connect internalsite.example.com:443 2>/dev/null | openssl x509 -noout -dates notBefore=Nov 30 00:00:00 2012 GMT notAfter=Mar 30 12:00:00 2016 GMT # For reference, the day I'm posting this is July 30th, 2014
Additionally, if I use cURL on a different computer, or connect via the browser (Firefox, Chrome, or IE), I can connect without error.
Also, I'm unable to connect with any version of cURL on my own computer; this includes cURL in Cygwin and cURL on Ubuntu inside a virtual machine, as well as the Windows version.
What might give rise to this behaviour?

lelandbatey almost 10 yearsI updated my cert bundle using the one from the curl devs, and I even re-installed curl. Neither of those things resolved the problems I'm having.

Paolo Stefan over 4 yearsThis seems not to work (anymore?). I've had this issue on an Ubuntu 16 machine and another Ubuntu 16 was working, but copying the file and telling curl to use it didn't help in any way.
