TLS 1.2与SQL Server 2014的通信

本文介绍了TLS 1.2与SQL Server 2014的通信的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我们有一个带有2.0框架的客户端（桌面）应用程序。此应用程序正在与SQL Server 2014进行通信。我们需要在客户端和数据库服务器之间启用TLS1.2通信。我们启用了TLS 1.2& TLS1.0 SChanels在数据库服务器机器中并在客户端机器（Windows 7操作系统）中启用相同功能。当我们运行应用程序默认情况下它是与TLS 1.2的通信。

We have a client(desktop) application with 2.0 framework. This application is communicating with SQL Server 2014. We have a requirement to enable the TLS1.2 communication between client and DB server. we have enable TLS 1.2 & TLS1.0 SChanels in DB server machine and enable same in client machine(windows 7 OS). When we run the application It is comuunication with TLS 1.2 by default.

现在我们将客户端应用程序frameowrk升级到4.0并测试与DB服务器的通信。测试时我发现它正在使用TLS1.0与SQL服务器进行通信。我没有为客户端应用更新框架版本。如果我将版本降级为2.0，它再次与TLS1.2进行通信。我用4.7.2进行了测试，它也以同样的方式进行测试。我得到一些链接说它取决于操作系统不在上。 （stackoverflow/questions/38275135/does-net-framework-2-0-support-tls1-1)

Now we are upgraded the client application frameowrk to 4.0 and test the communication with DB server. While testing i found It is using TLS1.0 to comminicate with SQL server. I did`t made any code chnages just i updated the framework version for the client application.If i degrade the version to 2.0 it is again communicating with TLS1.2. I tested with 4.7.2 also it is also wrking in the same way. I got some links says it is depends upon the OS not on the . (stackoverflow/questions/38275135/does-net-framework-2-0-support-tls1-1)

推荐答案

嗨p_kiran，

Hi p_kiran,

感谢您在此发帖。

据我所知， framework 2.0不支持TLS 1.2。你能提供更多细节吗？什么是运行时的框架版本？

As I know, framework 2.0 do not suppoet TLS 1.2. Could you provide more details about that? What is the framework version on the runtime?

最好的问候，
