We need a few pieces of code for further understanding!

Can you guide me? Suppose I am a newbie who knows nothing about the tool you have created and wants to start a small project with Wolfcrypt on Arduino. I have read the entire document many times, but I don't know why Arduino generates a series of errors for its own sake and then gives the error again after fixing the error.

• version of wolfssl on arduino: 5.8.2
• ESP8266 with WiFi
• running example of wolfssl: wolfssl_version.ino
• latest arduino software
  only open the example file of arduino & compile, the

Error of Arduino look like this:

In file included from c:\Users\cloudi\Documents\Arduino\libraries\wolfssl\src/wolfssl/ssl.h:262,

Maybe this first question has an easy answer that I haven't paid attention to until now.
but
I asked a very important question at the next, that I really need help with. Perhaps my question will be the question of many others in the near future.

Watch this video first : https://www.youtube.com/watch?v=dAZjWDZDFNo&t=32s
I am looking for a piece of code that uses SSL or (it is better use TLS) with quantum post encryption for secure communication with the server, exactly the same as the introduced video.
we need it for ESP8266 & we have vs code & arduino IDE & thonny tools
also we want it, to implement server & client source code to accept the only post quantum key exchange (ML-KEM)
semi similar to https://github.com/nichelaboratory/ESP32-WifiSecure-Retrieve-Data-Using-SSL/blob/main/ESP32_WifiSecure_Retrieve_Data_Using_SSL/ESP32_WifiSecure_Retrieve_Data_Using_SSL.ino

until now, are we have SSL or TLS post quantum ready sorce code for ESP8266?
if not, can we implement one of those for our client/server? if yes, How?
also, i see this post: wolfSSL/wolfssl#8374

can anyone help me at this point??, thank's alot.

Hello @BuggerBag

Thanks for contacting wolfSSL Support. I've requested a review of your questions by our engineers. Could you tell us a bit about your project? Feel free to use our support portal by emailing support@wolfssl.com for a more private discussion.

Kind regards,
@embhorn - wolfSSL Support

Hello, thank you very much for your quick response.
My team and I have worked on many weaknesses in today's security protocols and are currently launching a huge IoT project.
Currently, two famous companies from America are partnering with us and we would like to do our research and industrial work efficiently, although we have already started the research work.

Hello @BuggerBag and thank you for your interested in wolfSSL for Arduino!

We are aware that the current published 5.8.2 Arduino-wolfSSL has problems with some targets such as the ESP8266.

Since that release, there have been many improvements. See wolfSSL/wolfssl#9091

If you'd like to test drive the Arduino library before the next release containing those fixes, see the install script in IDE/ARDUINO.

For the list of boards being tested by GitHub workflows, see the Arduino/sketches/board_list.txt, which includes ESP8266.

You will have a better experience using the native Espressif ESP-IDF toolchain, but the Arduino environment should be ok.

We also have this video for getting started with wolfSSL on the ESP32: https://www.youtube.com/watch?v=CzwA3ZBZBZ8

Post Quantum on the Espressif devices, see this blog: https://www.wolfssl.com/post-quantum-key-share-on-the-espressif-esp32/ .

Although the ESP32 is named, the PQ configs should work on the ESP8266 as well. It's all about the user_settings.h file.

I also have Espressif-specific updates pending in wolfSSL/wolfssl#9243 and wolfSSL/wolfssl#9242 .

The TLS examples can be found in the Espressif client and server. See also the core client and server examples.

The example include setting up wolfSSL secure connections. The Espressif examples use test certificates referenced in user settings.

As the ESP8266 is NRND you may be interested in the ESP32-C2.

Hello @gojimmypi . Thank you very much for your time and I am very grateful for this valuable help.
Considering the supported boards you introduced, does the ESP32 chip have to be from the Expressif brand? There are different versions on the market, most of which may not be from this brand.
When will the new version of wolfssl be released so we can use it?

I will check, thank's alot.

[gojimmypi]

does the ESP32 chip have to be from the Expressif brand?

Do you have an example of the chip not being from Espressif? Given the price point, it would seem unlikely there would be alternatives.

Perhaps you mean dev boards? As far as I know, all the different makers of dev boards use genuine Espressif chips. There is however, a wide variety of implementations on each board for various manuifacturers. The most annoying thing is that not everyone implements the programming circuitry properly. The result is those boards need a convoluted, manually process of holding and releasing buttons at programming time. All dev boards from Espressif that I've used can be programmed completely hands-off. Other dev boards may also include additional PSRAM or other features.

In any case, wolfSSL is expected to run on all boards, all chips.

When will the new version of wolfssl be released so we can use it?

The wolfssl library is typically released every few months or so. The last release was July 7. The Arduino publish typically occurs a short time after the wolfssl release.

Your interpretation of my post was correct. I was in a hurry, so I had to convey the message this way.
