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 macOS 10.7 or later) and Schannel support "P12" for
       PKCS#12-encoded files. GnuTLS supports P12 starting with curl 8.11.0.

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

       Using this option multiple times makes the last set string override the previous ones.  Set  it  to  NULL
       restores back to internal default.

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_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

       Added in curl 7.9.3
