|
You will need to approve a security exception in your browser. This is because of a self signed
|

|
|
certificate; this will be always the case, unless you preload the CA root into your browser/system
|
|
|
|
|
as trusted.

|
You can generate a new certificate using the OpenSSL command line tool:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
openssl req -newkey rsa:2048 -nodes -keyout prvtkey.pem -x509 -days 3650 -out cacert.pem -subj "/CN=ESP32 HTTPS server example"
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Expiry time and metadata fields can be adjusted in the invocation.
|
|
|
|
|
|
|
|
|
|
Please see the openssl man pages (man openssl-req) for more details.
|
|
|
|
|
|
|
|
|
|
It is **strongly recommended** to not reuse the example certificate in your application;
|
|
|
|
|
it is included only for demonstration.
