- Added a config option to set the minimum Certificate Verification
mode to Optional
- When this option is enabled, the peer (the client) certificate
is checked by the server, however the handshake continues even if
verification failed.
- By default, the peer certificate is not checked and ignored by the server.
Closes https://github.com/espressif/esp-idf/issues/8664
- Can be used to get connection or client information (SSL context)
- E.g. Client certificate, Socket FD, Connection state, etc.
- Added example callback for getting client certificate information in 'https_server/simple' example
