Can't enable TLS 1.2 on Windows 2008 SP2 (non R2)

    Question

  • Tried changing the register by following these instructions:

    https://social.msdn.microsoft.com/Forums/windowsserver/en-US/97e37a88-f7f8-424a-b8bd-e089f1bbea84/upgrade-winhttpdll-version-to-support-tls-11-and-tls-12-windows-2008-r2-and-windows-7?forum=winserver2008appcompatabilityandcertification

    Used IIS_Crypto and it never shows TLS 1.1 nor TLS 1.2 to select.

    My Windows is up to date.

    I'm trying to use winhttp to connect to a https (WHM/cpanel API) but they only support TLS 1.2. So, I always get this error:

    WinHttp.WinHttpRequest error '80072f8f'

    A security error occurred

    Any ideas?

  • Have you added the registry keys mentioned here: https://support.microsoft.com/en-us/help/4019276/update-to-add-support-for-tls-1-1-and-tls-1-2-in-windows

     

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2

     

    Subkey

    Description

    Default

    Client

    Controls the use of TLS 1.1 on the client

    Enabled

    Server

    Controls the use of TLS 1.1 on the server

    Enabled

    DisabledByDefault

    Flag to disable TLS 1.1 by default

    Enabled

     

     

    NOTE: For TLS 1.2 to be enabled and negotiated, you must create the DisabledByDefault DWORD entry in the appropriate subkey (Client, Server), and then change the DWORD value to 0. 

     

    can you share the version of SCHANNEL.DLL

  • Thank you Kaushal for the answer!

    My schannel.dll (at c:\windows\system32\, right?) version is 6.0.6022.24383

    And I already added the registry keys as mentioned:
