> Far better would be the snippet of Common Lisp that reads random from getrandom(), and then /dev/urandom. Yup. Here's an example of the latter (I don't have getrandom(2) on my machine): (defun random-bytes (len) (declare (type (integer 1) len)) (with-open-file (rand "/dev/urandom" :element-type 'unsigned-byte) (let ((buf (make-array len :element-type 'unsigned-byte))) (read-sequence buf rand) buf))) N.b.: I dashed this off quickly. Do not rely on it for security-sensitive code. Do not bet your life on it.
