This post will address what to look for and how to enable TLS 1.2 as the nonpayment protocol for Windows Server 2012 R2 or older. IMPORTANT: As always and it ’ s worth repeat, you need to backup your current register settings before attempting any of these changes on your servers .
Enable TLS 1.2 on Windows Servers 2008 SP2 or later
The blanket statement to enable your TLS 1.2 on your server from Windows Server 2008 SP2 or late. Microsoft provided an update to add support for TLS 1.1 and TLS 1.2 for Windows Server 2008, but it requires Windows Server 2008 SP2 installed. so just to submit the obvious, TLS 1.1 and TLS 1.2 are not supported for 32-bit Windows Server 2008 SP1 .
- launching regedit.exe .
- In register, go to :
- Create a newly DWORD entrance with a name TLS 1.2 and create another subkey Client and Server .
- Under the subkey Server, make another DWORD Enabled with a value of 1 .
- placid under the subkey Server, create a DWORD DisabledByDefault with a measure of 0 .
- You must create a subkey DisabledByDefault entrance in the appropriate subkey ( Client, Server ) and set the DWORD measure to 0 since this entrance is set to 1 by default.
- Reboot the server and quiz .
Enable TLS 1.2 on .NET Framework 3.5 (including 2.0)
.NET Framework 3.5 or earlier did not originally provide support of applications to use TLS System Default Versions as a cryptanalytic protocol. however, for Windows Server 2012 R2, check if KB3154520 is installed ( or KB3154519 for Windows Server 2012 ; KB3154518 for Windows Server 2008 R2 ; KB3154517 for Windows Server 2008 SP2 ) .
How to check the KB updates
- Right-click on the Windows button and choice Programs and Features.
- On Programs and Features window, click onthe View installed updates on the forget paneling.
- You will see a list of the updates that you can narrow down or do a very specific search by using the Search Installed Updates box. You can type in the KB number ( i, “ KB3154520 ” ).
- If the corresponding KB is already installed, we just need to enable it via register change. differently, you need to install the patch from either of the links for Windows Server 2012 R2 ( or use the same match links above for earlier versions of Windows Server ) .
- launch regedit.exe .
- Go to :
- Create a new entrance SystemDefaultTlsVersions with a DWORD respect set to 1 .
- Create a new entrance SchUseStrongCrypto with a DWORD rate set to 1 .
- Go to :
- Create a newly entry SystemDefaultTlsVersions with a DWORD value set to 1 .
- Create a raw entry SchUseStrongCrypto with a DWORD value set to 1 .
- For 64-bit OS, the like changes besides needed for the stick to locations :
- Create a fresh entry SystemDefaultTlsVersions with a DWORD value set to 1 .
- Create a new entry SchUseStrongCrypto with a DWORD value set to 1 .
- Go to :
- Create a new entrance SystemDefaultTlsVersions with a DWORD value set to 1 .
- Create a new entry SchUseStrongCrypto with a DWORD rate set to 1 .
- test .
Enable TLS 1.2 as default for WinHTTP
This may be applicable for any classic ASP or VB6 applications that use WinHTTP. Prior to Windows 10 and Windows Server 2016, TLS 1.1 or 1.2 is not enabled by default for client-server communications through WinHTTP. To set TLS 1.2 by default, do the come :
- Create a register entry DefaultSecureProtocols on the pursue location :
- Set the DWORD value to 800 for TLS 1.2 .
- For 64-bit OS, repeat step 1 and 2 on the following localization :
- Reboot the server and test .
Windows 10 and Windows Server 2016/2019 support TLS 1.2 for client-server communications by using WinHTTP.
