I can't remember the exact details, so could someone give me a quick 
refresher- which of the following are considered ok under ITAR?

	MD5 as a checksum
	keyed MD5 for authentication
	keyed MD5 as a stream cypher

Thanks
Simon

(defun modexpt (x y n)  "computes (x^y) mod n"
  (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))))
