Detailed Description

WiFiClientSecure-compatible TLS/TCP client for Zephyr RTOS. Header-only implementation — just include this file.

Typical usage: WiFiClientSecure client; client.setCACert(ca_pem, ca_pem_len); // optional: verify server client.setCertificate(cert_pem, cert_pem_len); // optional: mutual TLS client.setPrivateKey(key_pem, key_pem_len); // optional: mutual TLS client.connect("example.com", 443);
