I'm trying to encrypt some password using TripleDES-encryption here...
I've followed the documentation for the mcrypt-libraries, but I get a
warning (all though it -does- encrypt the text) every time I try to
encrypt something;

Warning: attempt to use an empty IV, which is NOT recommend

My encrypt line looks like this:
$crypted_password = mcrypt_ecb(MCRYPT_TripleDES, "secret key", $password, 

If I echo bin2hex($crypted_password) i get output, so it seems to
work... I'd just like to know why this warning appears...

I'm using Apache 1.3.23, php 4.1.1. Here's the mcrypt version
Mcrypt v.2.5.10 (i686-pc-linux-gnu)
Linked against libmcrypt v.2.4
(the mcrypt-packages are the current available libmcrypt/mcrypt-packages
 in debian testing)
