Simple TLS/SSL Ethernet WebServer, HTTP Client and WebSocket Client library for for AVR, Portenta_H7, Teensy, SAM DUE, SAMD21, SAMD51, STM32F/L/H/G/WB/MP1, nRF52 and RASPBERRY_PI_PICO boards using Ethernet shields W5100, W5200, W5500, ENC28J60 or Teensy 4.1 NativeEthernet/QNEthernet. It now supports Ethernet TLS/SSL Client. The library supports HTTP/HTTPS GET and POST requests, provides argument parsing, handles one client at a time. It supports Arduino boards (SAM DUE, Atmel SAM3X8E ARM Cortex-M3, SAMD21, SAMD51, ESP8266, ESP32, Adafruit nRF52, Teensy boards) using Wiznet W5x00 or ENC28J60 network shields. Ethernet_Generic library is used as default for W5x00 with custom SPI
