NAME

       CURLOPT_SSLENGINE - SSL engine identifier

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLENGINE, char *id);

DESCRIPTION

       Pass a pointer to a null-terminated string as parameter. It will be used as the identifier
       for the crypto engine you want to use for your private key.

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

       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_SSLENGINE, "dynamic");
         ret = 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 found.

       CURLE_SSL_ENGINE_NOTFOUND - Engine not  found,  or  OpenSSL  was  not  built  with  engine
       support.

       CURLE_SSL_ENGINE_INITFAILED - Engine found but initialization failed.

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