Works fine for me on Linux, I saw this bug before and then it was a
Windows issue too. I don't have a development setup for Windows here so
I can't really help to track down this problem.

Description:
------------
Just changed from php4 to php5. Now mcrypt decryption does not work
anymore. The function returns the encrypted data instead of the
decrypted.
The testcode is the example from the mdecrypt_generic function
documentation.
using php.ini-recommended and only changed the following
display_errors = On
display_startup_errors = On
extensions_dir = ...
loaded extra modules:
gd2, mbstring, mcrypt, mysql, exif
Reproduce code:
---------------
<?php
$key = 'this is a very long key...';
$plain_text = 'very important data';
$td = mcrypt_module_open('des', '', 'ecb','');
$key = substr($key, 0, mcrypt_enc_get_key_size($td));
$iv_size = mcrypt_enc_get_iv_size($td);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
if (mcrypt_generic_init($td, $key, $iv) != -1) {
$c_t = mcrypt_generic($td, $plain_text);
mcrypt_generic_deinit($td);
mcrypt_generic_init($td, $key, $iv);
$p_t = mdecrypt_generic($td, $c_t);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
}
if (strncmp($p_t, $plain_text, strlen($plain_text)) == 0)
echo "ok";
else
echo "error";
?>
Expected result:
----------------
the result should be: ok
Actual result:
--------------
the result is: error
