That's xdrp-keygen, right?

Looking at the code, the key generated by this tool is signed by the
well-known private key, in exactly the same way as described in the
original vulnerability report.  Microsoft's RDP client, at least, will take
this signature to mean that the server's key is allowed to change, and
presumably other clients such as rdesktop do the same for compatibility.

Does anybody know what happens if you feed xrdp a self-signed or
genuinely-signed key?  (Is there actually any way to do so?  It doesn't
look as if the key is stored in a standard format.)

  Harry.
