IPSEC == end of firewalls

[Simon Spero]

This thread definitely belongs as cypherpunks, as the whole point of the

achieve. 

What do you need as well as crypto before you can remove all firewalls?

  (cond ((= y 0) 1) 	((= y 1) (mod x n))
	((evenp y) (mod (expt (modexpt x (/ y 2) n) 2) n))
	(t (mod (* x (modexpt x (1- y) n)) n))))
