No all it would do is give a false sense of security. No matter how you encrypt / obfuscate it on
the box, it needs to be sent clear when its used.
 
All it would take is a simple sniffer and you would get it.
 
Its wrong to give people a false sense of security.

	[Sorry to resurrect this, but I have a kooky idea. I have no illusions about
	implementing it, it's more intended to nail down my understanding of this
	issue.]
	
	Is it possible that the problem with this discussion is that everyone
	assumes some sort of fixed obfuscation algorithm in the m0n0wall sources?
	Instead, couldn't an installed m0n0wall store a secret key that is
	notincluded in the
	config.xml file? The secret would be set from the physical console menu, and
	stored elsewhere in the installed m0n0wall image.
	
	Whenever DynDNS or PPP or anything else needs a password, the local secret
	key would be used to decrypt (in memory only) the appropriate config.xmlentry.
	
	As I said, it's a kooky idea and probably breaks a bunch of design goals,
	but would it work?
