I want to add below cipher suits in my Windows Server 2008 R2 SP1 Standard as required by our security team. As per my research (see below links) these cipher suits are not supported by Windows Server 2008 R2 and are only available in Windows Server 2016. Can someone conform me this? Also please let me know if there is any possibility to use these ciphers.
