NAME¶

CURLOPT_SSLENGINE_DEFAULT - make SSL engine default

SYNOPSIS¶

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLENGINE_DEFAULT, long val);

DESCRIPTION¶

Pass a long set to 1 to make the already specified crypto engine the default for (asymmetric) crypto operations.

This option has no effect unless set after CURLOPT_SSLENGINE(3).

DEFAULT¶

None

PROTOCOLS¶

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

This option works only with the following TLS backends: OpenSSL

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_SSLENGINE, "dynamic");


    curl_easy_setopt(curl, CURLOPT_SSLENGINE_DEFAULT, 1L);


    res = curl_easy_perform(curl);


    curl_easy_cleanup(curl);


  }
}

AVAILABILITY¶

Only if the SSL backend is OpenSSL built with engine support.

RETURN VALUE¶

CURLE_OK - Engine set as default.

CURLE_SSL_ENGINE_SETFAILED - Engine could not be set as default.

CURLE_NOT_BUILT_IN - Option not built in, OpenSSL is not the SSL backend.

CURLE_UNKNOWN_OPTION - Option not recognized.

CURLE_OUT_OF_MEMORY - Insufficient heap space.
