Secure Layer (SSL/TLS) TCP Client featuring protocol upgrade capability and optimized memory usage for resource-constrained boards.
This professional-grade library provides a robust SSL/TLS layer for network communication, designed to support modern 32-bit Arduino platforms (ESP8266, ESP32, RP2040, Teensy, etc.). It acts as a transparent wrapper, enabling secure connectivity over standard clients (WiFiClient, EthernetClient). Key advantages include support for dynamic memory allocation (PSRAM) on compatible boards, memory-saving build configurations (Insecure Only), and the ability to upgrade an existing plain TCP connection to TLS seamlessly.
