I got one of the disks. Amusing disclaimers on the back. Haven't tried reading it yet. When I talked to Phil Karn months ago about IP encryption, he was talking about encrypting each packet independently - I guess you have to do that with IP since it's not a reliable protocol. But it sounded a little risky to me - maybe vulnerable to attack via known bits at the start of each encrypted section. Encrypting at the TCP level would allow inter-packet mixing, but then you miss all the UDP protocols such as (old) NFS. Maybe you could post a quick summary of the encryption mode used? --- Jef
