get-schannel-ciphers

List enabled SCHANNEL ciphers (Windows).

If you run this in Kudu (Azure App Service), you'll need to hit Enter to get any output (hangs on Console.ReadKey()).

UPDATE Feb-22 2018:

PowerShell on Windows 10/Server 2016 now has a Get-TlsCipherSuite cmdlet. Use that instead. https://docs.microsoft.com/en-us/powershell/module/tls/get-tlsciphersuite?view=win10-ps

I'm pretty sure the warning below still applies, but can't confirm.

Word of warning

Windows needs a reboot every time you enable/disable/change_cipher_order. The cipher suite will still show up in this list even if the system was not rebooted (i.e. the cipher suite is not yet active but shows up).
