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

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_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");


    res = 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.
