Auto Handshake certificate ethernet

Orphic · August 18, 2021, 4:35pm

hello friend
how can I use this function so that it recevies Auto handshake without certificate???
exp : when using class esp8266secure can get data handshake & its dosent need cert.h class or function & gets the certificate automaticaly the same as chrome browser when searching the web site
what library do you use for ssl and ethernet (Auto Handshake) ?
thx..

Juraj · August 18, 2021, 6:53pm

what library do you use for secure connection over Ethernet? and what board do you use?

Orphic · August 18, 2021, 8:22pm

My board : esp8266-12F
Ethernet Controller : ENC28j60
Lib : UIPEthernet for ethernet but i can change it if it helps ....
now
EthernetClient sslClient;
BearSSLClient client(sslClient);
.
.
.
client.connect(Link , 443);

but this code can not handshake certificate ssl & need hard code certificate statics

Juraj · August 19, 2021, 5:52am

use the new lwIP_enc28j60 bundled with esp8266 arduino. it adds a new network interface and you work with it over the WiFi library same way as with the STA interface and SoftAP interface

Orphic · August 19, 2021, 7:54am

do you have an example for this library ?

Juraj · August 19, 2021, 8:12am

in ESP8266WiFi library examples section in Arduino IDE

Orphic · August 19, 2021, 11:53am

I have checked all the libraries none of them handshakes the certificate

Juraj · August 19, 2021, 1:38pm

if you use the lwIP_enc28j60 then you can use the same code as you used for WiFi

why do you use EthermetENC + SSLClient and not the lwIP_enc28j60 library?

do you have a code which works over ESP8266WiFi library?

Orphic · August 20, 2021, 10:08am

i haven't used these libraries (sslclient ) & comment this line
i want used lwIP_enc28j60 & ethernetclient

Orphic · August 20, 2021, 10:15am

yes my code for ESP8266WiFi :

WiFiClientSecure espClient;
PubSubClient client(espClient);
espClient.setInsecure();

if (!client.connected()) {
Serial.print("Attempting MQTT connection...");
// Attempt to connect

if (client.connect("", Orphic.Server_User, Orphic.Server_Pass))
{ //serial //user //pass

.
.
.

i have used these codes for connection with wifi
and it works with out any problems
but i have problems with getting certificate ssl (Handshake) with ethernet (enc28j60)

Orphic · August 20, 2021, 10:21am

isnt "lwIP_enc28j60 " library the EthernetENC ?? or are they different ?
the examples for "lwIP_enc28j60 " library are mostly from "EthernetENC"

Juraj · August 20, 2021, 10:44am

totally and completely different libraries.
lwIP_enc28j60 is part of the esp8266 core.

you can connect. 400 Bad request is a response from the server telling you that the request doesn't match the HTTP protocol

try to remove all that " + "

Orphic · August 20, 2021, 7:57pm

yes , i connect to server
but i can't get data from server

i edited my code as you said
GET /gadget/skeleton?serial=swr012108031138&uid=95f916e0-56d6-487f-82dd-da75b14081cb HTTP/1.1 HTTP/1.1\r\nHost: assess.mmaviot.com\r\nConnection: close\r\n\r\n

but this code worked with wifi mode before.
i dont know where the problem is , only the request class has changed & the request method is the one that worked before ...
