CURLOPT_SSLCERTTYPE(3)     curl_easy_setopt options     CURLOPT_SSLCERTTYPE(3)

NAME
       CURLOPT_SSLCERTTYPE - specify type of the client SSL certificate

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Pass a pointer to a null-terminated string as parameter. The string
       should be the format of your certificate. Supported formats are "PEM"
       and "DER", except with Secure Transport. OpenSSL (versions 0.9.3 and
       later) and Secure Transport (on iOS 5 or later, or OS X 10.7 or later)
       also support "P12" for PKCS#12-encoded files.

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

DEFAULT
       "PEM"

PROTOCOLS
       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         curl_easy_setopt(curl, CURLOPT_SSLCERT, "client.pem");
         curl_easy_setopt(curl, CURLOPT_SSLCERTTYPE, "PEM");
         curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
         curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       If built TLS enabled. Added in 7.9.3

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.
