[AG-TECH] vic and rat encryption

	You may be better off using Rjindael encryption, which is normally used 
on AG Venues when setting the 'encryption' option in the venue server 
	A Rjindael key is passed to VIC and RAT as 'Rjindael/passphrase' where 
passphrase should be something random and unguessable, and distributed 
to those needing the key to enter manually. There's a program for Debian 
called 'pwgen' that I've used to generate a passphrase before. For 
manually entering the key, you would probably just disable the venue 
encryption and manually key it in. For a DES key, just use a passphrase 
that doesn't start with a string 'Rjindael/'.
	Of course you can also use certificates to secure a venue too, so not 
just anyone can enter and obtain the encryption key.
