Payment gateways are now requiring commmunication via TLS 1.2. This plugin will test your webserver for compatibility to ensure there is no outage in your ecommerce application.
If your server is not able to communicate via TLS 1.2, you will be shown the appropriate steps to take to upgrade the server version of OpenSSL, PHP, or direct you to update the SSLVERSION of CURL.
The plugin currently offers testing via these API Endpoints:
* PayPal (https://tlstest.paypal.com/)
* How’s My SSL? (https://www.howsmyssl.com/a/check)
Testing against these API Endpoints should validate compatibility for other gateways and APIs, even if you are not using PayPal, for example, on your ecommerce application. However, we do plan to add more tests for API Endpoints provided by popular gateways.
