Hi Oleg - you are right, I can't get the .p12 to work with command-line curl either. I'm sure it used to many years ago.

But the new curl's (I've tried 7.45 and 7.46), when using --cert filename.p12:password, both fail saying:

  ... could not load PEM client certificate, OpenSSL error error:0906D06C ...

Anyway, switching to .pem works fine in pycurl.

Many thanks!

On the other hand it looks like libcurl should support p12 format. Are you able to connect to your server using your certificate using curl
7.46.0 program obtained from http://curl.haxx.se/download.html ?
