Friends

I want to use cURL to access a remote server, and I need to identify myself using a private key, otherwise the remote server gives a 401 "Unauthorized".

I'm on Windows 7 (work machine, not my choice) and my private key is installed on my computer. I'm not permitted to access it directly, but I'm confident it's installed in the certificate store correctly. So I want to specify the *public* key in the cURL command, and let the operating system work out which private key to use.

I've given the public key to the remote server, and they've accepted it and installed it.

So I'm doing this:

        curl --verbose --cert "my-public-cert.pem" https://secure.server.com/path

...but it's not working, I'm getting a 58 error:

        * Trying 12.34.56.78...
        * Connected to secure.server.com (12.34.56.78) port 443 (#0)
        * unable to use client certificate (no key found or wrong pass phrase?)
        * Closing connection 0
        curl: (58) unable to use client certificate (no key found or wrong pass phrase?)

Am I doing something wrong? Is there a way to send a cURL request over SSL, if I can't access the private key directly but the operating system has the private key installed? Or is this just impossible?

Many thanks,
        Brendan.

PS - Full disclosure - I posted this question to SuperUser (http://superuser.com/questions/884812/how-to-use-pfx-in-certificate-store-in-curl-for-windows-7) a couple of days ago, but have not received any answers.
