note 88687 added to function.mcrypt-encrypt

bantam (below) has written a bad example. He was base64 decoding even though he never base64 encoded. In addition to that, the trimming is not effective and the cipher block mode is not secure. Here is a very good approach to encrypt / decrypt data. <?php $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC); $iv = mcrypt_create_iv($iv_size,MCRYPT_RAND); $key = "my secret key"; $text = "I discovered a way to crack into the White House."; // Just kidding :P $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256,$key,$text, MCRYPT_MODE_CBC,$iv); $decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key,$crypttext, MCRYPT_MODE_CBC,$iv); echo rtrim($decrypttext,"\0"); ?> ---- Server IP: 62.237.7.3 Probable Submitter: 81.175.154.102 ---- Manual Page -- http://www.php.net/manual/en/function.mcrypt-encrypt.php Edit -- https://master.php.net/note/edit/88687 Del: integrated -- https://master.php.net/note/delete/88687/integrated Del: useless -- https://master.php.net/note/delete/88687/useless Del: bad code -- https://master.php.net/note/delete/88687/bad+code Del: spam -- https://master.php.net/note/delete/88687/spam Del: non-english -- https://master.php.net/note/delete/88687/non-english Del: in docs -- https://master.php.net/note/delete/88687/in+docs Del: other reasons-- https://master.php.net/note/delete/88687 Reject -- https://master.php.net/note/reject/88687 Search -- https://master.php.net/manage/user-notes.php
