when you open a Remote Desktop rdp file you will get a warning: Unknown publisher.

PS D:\> cd CERT:\
PS Cert:\LocalMachine\My\> dir


   PSParentPath: Microsoft.PowerShell.Security\Certificate::LocalMachine\My

----------                                -------

rdpsign /sha256 E09234CE44B9198A0CD5D1672C19C76D8445C21A  "D:\Data\myHost.rdp"

Note: If you got an error: 0x8007000d The certificate needs at least the Keyusage: Digital Signatur and the ExtentedKeyUsage: Serverauthentification (1.3.6.1.5.5.7.3.1), Clientauthentification (1.3.6.1.5.5.7.3.2)
