+OpenSSL 3 has deprecated support for custom engines with a recommendation to
+switch to its new provider model. The `clientCertEngine` option for
+`https.request()`, [`tls.createSecureContext()`][], and [`tls.createServer()`][];
+the `privateKeyEngine` and `privateKeyIdentifier` for [`tls.createSecureContext()`][];
+and [`crypto.setEngine()`][] all depend on this functionality from OpenSSL.
