[lwip-users] http with minimum TLS example

Hi I have used http so far but I would like to use https. In httpd.c file is example: httpd_inits(struct altcp_tls_config *conf) My question is what functions I must use before calling "httpd_inits()" to get proper struct altcp_tls_config *conf ? I want to use TLS without certificates with minimal

1. Check whether you have free these 20kB heaps and even try to increase it for testing. 2. Change the authentication type from RSA to ECDSA, now you are using it TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, try change to TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 or similar. > pon., 28 sty 2019 o
