note 69434 added to ref.mcrypt

For those looking a mysql_aes_decrypt, I was able to create this method, referencing rolf's aes_encrypt below. Since the aes_encrypt right bads n * blocksize with chr( 0 to 16 ), but is random based on the input string, we first decrypt the text, then rtrim chr(0 .. 16) depending on it's initial length :) mysql AES_DECRYPT() compatibly function for PHP : function mysql_aes_decrypt( $val, $ky = 's0ftd0c2oo6' ) { $mode = MCRYPT_MODE_ECB; $enc = MCRYPT_RIJNDAEL_128; $dec = @mcrypt_decrypt($enc, $ky, $val, $mode, @mcrypt_create_iv( @mcrypt_get_iv_size($enc, $mode), MCRYPT_DEV_URANDOM ) ); return rtrim( $dec, ( ( ord(substr( $dec, strlen( $dec )-1, 1 )) >= 0 and ord(substr( $dec, strlen( $dec )-1, 1 ) ) <= 16 ) ? chr(ord(substr( $dec, strlen( $dec )-1, 1 ))): null) ); } Please note that if the strlen($ky)>16 then this function will not be compatible. ---- Server IP: 66.163.161.117 Probable Submitter: 71.219.21.71 ---- Manual Page -- http://www.php.net/manual/en/ref.mcrypt.php Edit -- https://master.php.net/note/edit/69434 Del: integrated -- https://master.php.net/note/delete/69434/integrated Del: useless -- https://master.php.net/note/delete/69434/useless Del: bad code -- https://master.php.net/note/delete/69434/bad+code Del: spam -- https://master.php.net/note/delete/69434/spam Del: non-english -- https://master.php.net/note/delete/69434/non-english Del: in docs -- https://master.php.net/note/delete/69434/in+docs Del: other reasons-- https://master.php.net/note/delete/69434 Reject -- https://master.php.net/note/reject/69434 Search -- https://master.php.net/manage/user-notes.php
