But the individual who might be reading the server logs is hopefully
not dumb.

Hm. The actual string doesn't look like base64 here:

host = DYNAMIC/Xxx/x1xxXXXxXXxX1X1XXX

(x is a lower case letter, X is a capital, 1 a digit). Please note the
second slash which seems out of place here, right?

Unfortunately, I cannot change the secret on the remote side until end
of the week, when I will do so. I'll get back here.

The .adr files are as easily replaced as the .png files though.
