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))))
