SSL and Outdated TLS(1.0 and 1.1) for Web Service client application on .Net 3.5

Question

As per PCI, we need to stop using SSL and TLS(1.0 and 1.1 in certain implementation) from June 30th 2016 as per http://blog.securitymetrics.com/2015/04/pci-3-1-ssl-and-tls.html

Answer 1

Actually, you can use TLS 1.2 in Frameworks lower than 4.5 (at least I managed it in .NET Framework 4 client). Instead of using the classic command in order to set the Protocol as Tls12, you can bypass it by using the id for this protocol.

  ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
