We are a small software company in NYC. We have a couple of large companies that use a combination of web and client applications. We use ntwdblib to communicate with Microsoft SQL Server in our client server application. We are a Microsoft only platform. Recently we have been told by our clients that we will need to support TLS 1.2 on their SQL server. We are already fully compatible with TLS 1.2 on our web system however our old legacy product built with Microsoft client application tools does not support TLS 1.2. It is our understanding that ntwdblib has been deprecated long ago and that we should rewrite the db protocol which would be a big development effort for a our team. We are just starting to do research to see if there is a set of libraries that can support TLS 1.2 and do that with a minimum development effort. Does anybody have any suggestions for us?
