NAME

       CURLOPT_SSLCERT - set SSL client certificate

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT, char *cert);

DESCRIPTION

       Pass  a  pointer  to  a zero terminated string as parameter. The string should be the file
       name of your client certificate. The default format is "P12" on Secure Transport and "PEM"
       on other engines, and can be changed with CURLOPT_SSLCERTTYPE(3).

       With NSS or Secure Transport, this can also be the nickname of the certificate you wish to
       authenticate with as it is named in the security database. If you want to use a file  from
       the  current  directory,  please  precede it with "./" prefix, in order to avoid confusion
       with a nickname.

       (Schannel only)  Client  certificates  must  be  specified  by  a  path  expression  to  a
       certificate store. (Loading PFX is not supported; you can import it to a store first). You
       can use "<store location>\<store name>\<thumbprint>" to refer  to  a  certificate  in  the
       system              certificates              store,              for             example,
       "CurrentUser\MY\934a7ac6f8a5d579285a74fa61e19f23ddfe8d7a". Thumbprint is usually  a  SHA-1
       hex  string  which  you  can  see  in  certificate  details. Following store locations are
       supported: CurrentUser, LocalMachine,  CurrentService,  Services,  CurrentUserGroupPolicy,
       LocalMachineGroupPolicy, LocalMachineEnterprise.

       When  using  a client certificate, you most likely also need to provide a private key with
       CURLOPT_SSLKEY(3).

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

DEFAULT

       NULL

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_SSLKEY, "key.pem");
         curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

       If built TLS enabled.
