Add a secure SSL certificate and update Paypal for the changes they require

This is the notice I received: We’re contacting our merchants with some important information in response to an industry-wide security upgrade which is not unique to PayPal. This change involves upgrading Secure Sockets Layer (SSL) certificates over the course of 2015 and 2016. Our upgrade efforts for API endpoints are scheduled to start in June 2015. Because these changes are technical in nature, we advise that you consult with your partner, website vendor, or individuals responsible for your PayPal integration. They will be able to identify what, if any, changes are needed. Please forward the information below to your technical contact for evaluation. We are here to help your technical contact work through this to ensure you continue to process payments through your current integration with us. Full technical details can be found in our Merchant Security System Upgrade Guide. In addition, our 2015-2016 SSL Certificate Change microsite contains a schedule of our service upgrade plan.
