SSLClient is a simple library to add [TLS 1.2](https://www.websecurity.symantec.com/security-topics/what-is-ssl-tls-https) functionality to any network library implementing the [Arduino Client interface](https://www.arduino.cc/en/Reference/ClientConstructor), including the Arduino [EthernetClient](https://www.arduino.cc/en/Reference/EthernetClient) and [WiFiClient](https://www.arduino.cc/en/Reference/WiFiClient) classes (though it is better to prefer WiFClient.connectSSL if implemented). In other words, SSLClient implements encrypted communication through SSL on devices that do not otherwise support it.

In other words, SSLClient implements encrypted communication through SSL on devices that do not otherwise support it.
SSLClient has been tested on the SAMD21 and STM32 (in progress). SSClient does not currently support the ESP8266/ESP32 family (see [this issue](https://github.com/OPEnSLab-OSU/SSLClient/issues/5#issuecomment-569968546)).
