CURLOPT_PROXY_SSLKEY - private key file for HTTPS proxy client cert
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLKEY, char *keyfile);
Pass a pointer to a null-terminated string as parameter. The string should be the filename of your private key used for connecting to the HTTPS proxy. The default format is "PEM" and can be changed with CURLOPT_PROXY_SSLKEYTYPE(3).
(Windows, iOS and Mac OS X) This option is ignored by Secure Transport and Schannel SSL backends because they expect the private key to be already present in the key chain or PKCS#12 file containing the certificate.
The application does not have to keep the string around after setting this option.
