I’m pretty sure I tested an  amrecover  (not a whole amrestore)   with my 
setup,   where the server does the encryption.
And it worked,  I mean.   Or I wouldn’t have continued.

I might only have tested an amrecover  ON the server though,  and not on the 
client.  Mine are all connected,  so I guess
I figured I could recover onto the server & transport later   (more likely,  it 
just didn’t occur to me to test from a client).
Or maybe I did ….

Let us know how your test works.
