Example 2: Get the ECC curves that match a string, PowerShell, Get-TlsEccCurve -Name ‘Nist’, This generates the following output: NistP256 NistP384, This command gets all the ECC curves that have names that contain the string ‘Nist’ case-sensitive,
Accept pipeline input : True
· Navigate to Computer Configuration,Preferences,Windows Settings,Registry, Right-click Registry, Hover over New and select Collection Item, Rename the collection item to match the name of the curve, You’ll create one Registry Collection item for each registry key under HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Cryptography\ECCParameters,
· Hi Rudy, is it possible that you have a custom configuration defined in that registry key value? Windows Server 2016 supports the following curves by default, in the following order: curve25519, NistP256, NistP384 , This can be controlled via the “ECC Curve Order” group policy in Administrative Templates -> Network -> SSL Configuration Settings, ?
