note 47560 added to ref.mcrypt

Or, if you don't have the mcrypt library, you can just use these functions: <?php function Encrypt($string, $key) { $result = ''; for($i=1; $i<=strlen($string); $i++) { $char = substr($string, $i-1, 1); $keychar = substr($key, ($i % strlen($key))-1, 1); $char = chr(ord($char)+ord($keychar)); $result.=$char; } return $result; } function Decrypt($string, $key) { $result = ''; for($i=1; $i<=strlen($string); $i++) { $char = substr($string, $i-1, 1); $keychar = substr($key, ($i % strlen($key))-1, 1); $char = chr(ord($char)-ord($keychar)); $result.=$char; } return $result; } ?> It's very simple encryption, but as long as the key stays secret, very powerful. ---- Manual Page -- http://www.php.net/manual/en/ref.mcrypt.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47560 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47560&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47560&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47560&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47560&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47560&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47560&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47560&report=yes Search -- http://master.php.net/manage/user-notes.php
