mcrypt_decrypt causes Apache to crash?

Hi All,

I'm trying to implement encryption to protect data in my database. I
started by experimenting with the following code, just to make sure I
know how to encrypt and then decrypt but for some reaqson when I add
the line "$plaintext = mcrypt_decrypt(..." etc Apache crashes.

I'm using:

- PHP 4.3.2
- Apache 1.3.24
- Windows XP

Following is an except of my code:

$myqs=mysql_query($myq);
$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
$key = "This is a very secret key";

while ($myqr = mysql_fetch_array($myqs)){

$text = $myqr["entry"];
$crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text,
MCRYPT_MODE_ECB, $iv);
$plaintext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key,
$crypttext, MCRYPT_MODE_ECB);
echo $plaintext."<p>";
}

If I remove the line "$plaintext = mcrypt_decrypt(.." Apache doesn't
crash.

Anyone have any idea why this might be crashing?

Many thanks in advance!

Much warmth,

Murray

Hi, i have experienced the same problem. In my situation it was easy.
was using apache 1.3x.x but then i found that you can avoid thes
crashes using mcrypt with apache 2.0 and up. Hope this helps.
