note 96921 added to function.mt-srand

What about this for an example... (sorry for the funky line breaks but I have once more reported the bug on this issue of word wrapping to no avail) Intending to use it in passing a "semi-guaranteed" properly seeded random number to a client, then to capture input from the user which must be encrypted client side before being sent to the server again a) during the same session and, b) within a set time limit. for more reading also see: AES Rijndael enc/dec routines for javaScript developed and tested by Herbert Hanewinkel, http://www.hanewin.net/encrypt/aes/aes.htm <?php /* calling the function, prepping the data to send to the client... , who then uses it in a javascript implementation of AES Encrypt. */ function SHA256($str, $keyval=""){ if ($keyval!==""){//not null or empty $sHash = mhash(Constant('MHASH_SHA256'),$str, $keyval); }else{ $sHash = mhash(Constant('MHASH_SHA256'),$str); } // same as Binary 2 Hex conversion return implode(unpack('H*',$sHash),''); } /*--------------------------------------------------- Radomizing the random data with fixed data for the user and location If return value maximum is set to zero (0) the function uses mt_getrandmax If both retMin and retMax is zero (0) the function uses mt_rand w.o. limits *----------------------------------------------------*/ function local_prgn($retMin = 0, $retMax = 0){ // first get the session id of the request session $sSrv = session_id(); // the following is valid only on the current server $sSrv = implode(unpack($_SERVER['SERVER_NAME']. $_SERVER['SERVER_ADDR'].$sSrv),''); // the following applies only to the requesting client $sReq = implode(unpack($_SERVER['REMOTE_ADDR']. $_SERVER['REQUEST_TIME']),''); // get a SHA256 seed based on the current values $sSeed = SHA256($sSrv,$sReq); // get a random value based on the uniqueness of the seed above mt_srand($sSeed); // seed the random num gen // some error handling and checking if ($retMin > $retMax){ // swap vars if wrong order $rx = $retMax; $retMax = $retMin; $retMin = $rx; } else if ($retMin == $retMax){ //meaningless range, not very random //ensure for next check in this range $retMin = 0; $retMax = 0; } // select what we need to return if ((($retMax == 0)&&($retMax = mt_getrandmax))|| ($retMin==$retMax)){ return mt_getrandmax(); }else{ return mt_getrandmax($retMin,$retMax); } } ?> ---- Server IP: 80.67.10.226 Probable Submitter: 212.181.164.190 ---- Manual Page -- http://www.php.net/manual/en/function.mt-srand.php Edit -- https://master.php.net/note/edit/96921 Del: integrated -- https://master.php.net/note/delete/96921/integrated Del: useless -- https://master.php.net/note/delete/96921/useless Del: bad code -- https://master.php.net/note/delete/96921/bad+code Del: spam -- https://master.php.net/note/delete/96921/spam Del: non-english -- https://master.php.net/note/delete/96921/non-english Del: in docs -- https://master.php.net/note/delete/96921/in+docs Del: other reasons-- https://master.php.net/note/delete/96921 Reject -- https://master.php.net/note/reject/96921 Search -- https://master.php.net/manage/user-notes.php
