Curl - cannot connect using p12 certificate

Question

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

Answer 1

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.
