note 44688 added to function.mt-rand

The correct address of the inventor's FAQ is (http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/efaq.html). They state that Mersenne Twister may be used for cryptography if you do some post-processing: "Mersenne Twister is not cryptographically secure. (MT is based on a linear recursion. Any pseudorandom number sequence generated by a linear recursion is insecure, since from sufficiently long subsequence of the outputs, one can predict the rest of the outputs.) To make it secure, you need to use some Secure Hashing Algorithm with MT. For example, you may gather every eight words of outputs, and compress them into one word (thus the length of the output sequence is 1/8 of the original one)." ---- Manual Page -- http://www.php.net/manual/en/function.mt-rand.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+44688 Delete -- http://master.php.net/manage/user-notes.php?action=delete+44688&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+44688&report=yes Search -- http://master.php.net/manage/user-notes.php
