mcrypt_get_block_size
(PHP 3>= 3.0.8, PHP 4 , PHP 5) mcrypt_get_block_size -- Get the block size of the specified cipher
Descriptionint mcrypt_get_block_size ( int cipher ) int mcrypt_get_block_size ( string cipher, string module ) The first prototype is when linked against libmcrypt 2.2.x, the
second when linked against libmcrypt 2.4.x or 2.5.x.
mcrypt_get_block_size() is used to get the
size of a block of the specified cipher (in
combination with an encryption mode).
It is more useful to use the mcrypt_enc_get_block_size()
function as this uses the resource returned by
mcrypt_module_open().
This example shows how to use this function when linked against libmcrypt
2.4.x and 2.5.x.
Пример 1. mcrypt_get_block_size() example
<?php
echo
mcrypt_get_block_size
(
'tripledes'
,
'ecb'
);
?>
Prints:
8
