DJ Hi All,

DJ }

DJ I get the following PHP Warning in my logs, however, the code executes ok:

DJ [Wed Jul  9 10:25:49 2003] [error] PHP Warning:  mcrypt_generic_init(): Iv
DJ size incorrect; supplied length: 0, needed: 8 in
DJ /usr/local/apache/htdocs-uat-retail/include/nocheck.iostream.class.php on
DJ line 87

DJ I have read into mcrypt, tried a couple things, but nothing will get rid of
DJ that error.  Could someone show me what I've done wrong?

I use this to set iv to null so I don't need to worry about it :)

$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);

 $iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);

Ahh ok, I'll give that a try and let you know how it comes out.  Thanks!
