OSDonate and PayPal Users: You Must Get an SSL Certificate
If you're using OSDonate (or any software that integrates with PayPal), your site needs to use a valid SSL certificate starting on Friday, June 30.
PayPal have a post on their developer blog with details on this important change.
Here's the important section of the PayPal post:
The most secure protocol for sharing information on the web today is Transport Layer Security (TLS) version 1.2. PayPal is enabling support for TLS 1.2 for all secure connections and in 2016 will start requiring its use. You will need to verify that your environment supports TLS 1.2 and if necessary make appropriate updates. PayPal is updating its services to require TLS v1.2 for all HTTPS connections in June of 2017. After that time, all TLS v1.0 and TLS v1.1 API connections will be refused.
That's a lot of technical jargon. What does it mean in plain English? It means that starting in July, any site that tries to process PayPal payments without an SSL certificate will be refused. It will be impossible to use PayPal without an SSL on your site.
Help! I don't have an SSL!
Don't worry. The days of expensive SSL certificates are gone.
