/* tls_server_bearssl - simple BearSSL TLS server that outputs some statistics to a connecting client,
|
||||
* then closes the socket.
|
||||
*
|
||||
* Uses code from the server_basic example in BearSSL and the tls_server example.
|
||||
*
|
||||
* To test this program, connect to the ESP using openssl command line like this:
|
||||
*
|
||||
* openssl s_client -connect 192.168.66.209:800
|
||||
*
|
||||
* The openssl command line client will print some information for the (self-signed) server certificate,
|
||||
* then after a couple of seconds (validation) there will be a few lines of text output sent from the ESP.
|
||||
*
|
||||
* See the certificate.h and key.h files for private key & certificate, plus information for generation.
