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  zero  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.
