Quite awhile ago I proposed strengthening create-random-string with something that required cl-ssl as a dependency and it was correctly pointed out that some implementations do not play well with cl-ssl. Would using the strong-random function from ironclad be acceptable? E.g.

(defun create-random-string (&optional (n 10) (base 16))



  "Creates a random string using ironclad's strong-random function with base BASE and N digits"
    (setf crypto:*prng* (crypto:make-prng :fortuna))



    (subseq (with-output-to-string (s)
       (loop for i to n do

            (format s "~VR" base
                    (ironclad:strong-random 100000000000))))


            0 n))
