# NAME
|
|
|
|
CURLOPT_SSLENGINE - SSL engine identifier
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 is 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.
|
|
|
|
# DEFAULT
|
|
|
|
NULL
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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");
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}

# AVAILABILITY
|
|
|
|
Only if OpenSSL is 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.
|
|
|
|
CURLE_UNKNOWN_OPTION - Option not recognized.
|
|
|
|
CURLE_OUT_OF_MEMORY - Insufficient heap space.
