+# NAME
+
+CURLOPT_SSLENGINE - Set SSL engine or provider
+
+# 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 *engine* or *provider* you want to use for your private
+key. OpenSSL 1 had engines, OpenSSL 3 has providers.
+
+The application does not have to keep the string around after setting this
+option.
+
+When asking libcurl to use a provider, the application can also optionally
+provide a *property*, a set of name value pairs. Such a property can be
+specified separated from the name with a colon (`:`).
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# 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%
+
+# 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.
