#49561 [NEW]: mcrypt warns about having no IV in ECB mode
From: terrafrost@php.net
Operating system:
PHP version: 5.2.10
PHP Bug Type: mcrypt related
Bug description: mcrypt warns about having no IV in ECB mode
Description:
------------
mcrypt complains about their being no IV even if ECB mode is being used.
Since ECB mode doesn't use IVs, it seems like no such warning should be
produced.
Bug #43143 is fairly similar to this one, except that that one produced a
slightly different error. Also, that one was closed on the basis that it
had been fixed.
Reproduce code:
---------------
<?php
$td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_ECB, '');
mcrypt_generic_init($td, 'aaaaaaaaaaaaaaaa', '');
?>
Expected result:
----------------
I would expect that to just run its course and output nothing.
Actual result:
--------------
I get the following:
Warning: mcrypt_generic_init(): Iv size incorrect; supplied length: 0,
needed: 16 in C:\php\test.php on line 3
