note 101059 added to book.mcrypt

If you want a quick way to see what ciphers, modes, key, block and iv sizes are supported on your server, try something like the following. Note: I used this simple bash: locate libmcrypt from terminal on Mac OS X to determine the install paths to the algorithms and modes directories. Lots of function calls generate warnings for certain ciphers, hence the use of error suppression. <?php $modes = mcrypt_list_modes(); $algorithms = mcrypt_list_algorithms(); foreach($algorithms as $cipher) { echo "<h1 style=\"border-top:1px solid black;\">".$cipher."</h1>\n"; foreach($modes as $mode) { echo "<h3>".$mode."</h3>\n"; @$td = mcrypt_module_open( $cipher, '/usr/local/libmcrypt-2.5.8/modules/algorithms/', $mode, '/usr/local/libmcrypt-2.5.8/modules/modes/'); @$key_size = mcrypt_enc_get_key_size($td); @$block_size = mcrypt_get_block_size($cipher,$mode); @$iv_size = mcrypt_get_iv_size($cipher, $mode); @mcrypt_module_close($td); echo " <pre> key_size: ". ($key_size?$key_size:'n/a') ." block_size: ". ($block_size?$block_size:'n/a') ." iv_size: ". ($iv_size?$iv_size:'n/a') ." </pre>\n"; $td=NULL; $key_size=NULL; $block_size=NULL; $iv_size=NULL; } } ?> ---- Server IP: 64.71.164.2 Probable Submitter: 70.166.218.198 ---- Manual Page -- http://www.php.net/manual/en/book.mcrypt.php Edit -- https://master.php.net/note/edit/101059 Del: integrated -- https://master.php.net/note/delete/101059/integrated Del: useless -- https://master.php.net/note/delete/101059/useless Del: bad code -- https://master.php.net/note/delete/101059/bad+code Del: spam -- https://master.php.net/note/delete/101059/spam Del: non-english -- https://master.php.net/note/delete/101059/non-english Del: in docs -- https://master.php.net/note/delete/101059/in+docs Del: other reasons-- https://master.php.net/note/delete/101059 Reject -- https://master.php.net/note/reject/101059 Search -- https://master.php.net/manage/user-notes.php
