Can't enable SSL for ESP32: error: 'AcSSlFileHandler' has not been declared

[strocode]

Hi,

I'm trying to enable SSL for ESP32 - perhaps this isn't supported? I've scraped together a few hints from various posts.

I'm using platformio and versions described below.

The error I get on compile is:

In file included from src/main.cpp:17:

Code is:

  server.serveStatic("/", SPIFFS, "/");

  server.onSslFileRequest([](void * arg, const char *filename, uint8_t **buf) -> int {
    Serial.printf("SSL File: %s\n", filename);
    File file = SPIFFS.open(filename, "r");
    if(file){

      if(nbuf){
        size = file.read(nbuf, size);
        file.close();
        *buf = nbuf;
        return size;
      }
      file.close();
    }
    *buf = 0;
    return 0;
  }, NULL);

  // Start server
  server.beginSecure("/Cert.pem", "/Key.pem", NULL);
}

// Initialize SPIFFS
void initSPIFFS() {
  if (!SPIFFS.begin()) {
    Serial.println("An error has occurred while mounting SPIFFS");
  }
  Serial.println("SPIFFS mounted successfully");
}

void setup() {
  Serial.begin(115200);
  initWifi();
  initSPIFFS();
  initSecureWebserver();
}


void loop() {
  Serial.println("Wait 10s");
  delay(10000);
}

Did you ever fix this? I have the same issue AcSSlFileHandler has not been declared - that's the only error i get on compile. Everything else works for me.

I have defined #define ASYNC_TCP_SSL_ENABLED 1 at the top level before my includes
and generated my key and cert files.

[strocode]

No, never managed to fix it.

damn - i wonder why the devs have not added support for the ESP32. Works fine on my ESP8266

[dmarc1234]

It would be really good to get this supported as we have been using ESPAsyncWebServer for a number of years and the consensus of opinion is that webservers without security are a thing of the past.
@me-no-dev any chance this could be done in the near future ?

use https://github.com/yubox-node-org/AsyncTCPSock.git and https://github.com/yubox-node-org/ESPAsyncWebServer
remove: { "owner": "me-no-dev", "name": "ESPAsyncTCP", "version": "^1.2.2", "platforms": "espressif8266" }, { "owner": "me-no-dev", "name": "AsyncTCP", "version": "^1.1.1", "platforms": "espressif32" }, in library.json of ESPAsyncWebServer

[dmarc1234]

Hello, great to see that this is being looked at, thank you.

However I am a little confused, beginSecure() will now compile, as its included within AsyncTCP.h, but there is still no underlying code within AsyncTCP.cpp to start the process ie. there is no beginSecure() routine within AsyncTCP.cpp

What am I missing ?

[playmiel]

actually I thought the ssl part was added with AsyncTCPSock but no you can use this example https://github.com/Bmooij/AsyncTCP-https-server-example
otherwise or if you can merge this example with the current AsyncTCPSock

[dmarc1234]

Unfortunately not and the example provided does not include it either.

Digging a little deeper it looks like the ESP8266 version, ESPAsyncTCP, does include beginSecure() but the ESP32 version, AsyncTCP, does not so this functionality has never been implemented in this version of the library.

Not sure what to try next, any ideas ?

[chrisdiphoorn]

Maybe This library - AsyncTCP_SSL

[playmiel]

this library is for esp32 and includes beginsecure :https://github.com/Bmooij/AsyncTCP.git
