The quality of the key used for CIPE is probably unimportant. CIPE has
significant other weaknesses:


Personally I think CIPE should just be removed from Fedora. IPSEC is
ready, it is just a matter of integrating the tools. And IPSEC has a
chance of being reasonably secure.

(I actually use CIPE in production since it is so hard to deal with
IPSEC when the distribution lacks the necessarily tools. I only send
encrypted data over CIPE though, so I feel reasonably safe. I look
forward to migrating to IPSEC.)
