CURLOPT_SSLCERTTYPE(3)              libcurl             CURLOPT_SSLCERTTYPE(3)


NAME

       CURLOPT_SSLCERTTYPE - type of 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 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

       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.
