Curl - cannot connect using p12 certificate

I'm trying to collect some data using Curl, connecting to service that some external company provided. They, in addition to address itself, sent me p12 certificate file that is required to estabilish connection.

When I'm trying to use it with curl, I get following error:

#58: not supported file type 'P12' for certificate

So far I've tried updating curl and php-curl. Nothing changed.

My code:

...
curl_setopt($ch, CURLOPT_SSLCERT, 'cert_path');
curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'P12');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'my_pass');
...

Funny thing is that this code works on our production environment, while it doesn't work on my local machine (Linux Mint 16).

Found the solution.

Easiest way to do this is to extract .pem key and certificate from .p12 file.

For example (tested on linux):

openssl pkcs12 -in file.p12 -out file.key.pem -nocerts -nodes
openssl pkcs12 -in file.p12 -out file.crt.pem -clcerts -nokeys

Will create key/cert pair in current directory.

Now, to use it:

curl_setopt($ch, CURLOPT_SSLCERT, 'file.crt.pem');
curl_setopt($ch, CURLOPT_SSLKEY, 'file.key.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'pass');
curl_setopt($ch, CURLOPT_SSLKEYPASSWD, 'pass');

Where pass is the password from .p12 file.
