NAME

       CURLOPT_PROXY_SSLCERTTYPE - type of the proxy client SSL certificate

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERTTYPE, char *type);

DESCRIPTION

       Pass  a  pointer to a null-terminated string as parameter. The string should be the format
       of your client certificate used when connecting to an HTTPS proxy.

       Supported formats are "PEM" and "DER", except with Secure Transport or  Schannel.  OpenSSL
       (versions  0.9.3  and  later), Secure Transport (on iOS 5 or later, or OS X 10.7 or later)
       and Schannel support "P12" for PKCS#12-encoded files.

       The application does not have to keep the string around after setting this option.

DEFAULT

       "PEM"

PROTOCOLS

       This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

       This option works only with the following TLS backends: GnuTLS, OpenSSL, Schannel,  Secure
       Transport, mbedTLS and wolfSSL

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
           curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT, "client.pem");
           curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERTTYPE, "PEM");
           curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem");
           curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       Added in curl 7.52.0

RETURN VALUE

       Returns  CURLE_OK if TLS is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY
       if there was insufficient heap space.
