[PHP] mcrypt warning

[Dan Joseph]

Hi All,

        I have the following function:

                function encrypt ($x) {
                        $ini = parse_ini_file ($GLOBALS['INI_PATH']);
                    $td  = mcrypt_module_open ('tripledes', '', 'ecb', '');
                $iv  = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td),
MCRYPT_RIJNDAEL_256);

                    mcrypt_generic_init ($td, $ini["key"], $iv);

                        $encrypted_data = mcrypt_generic ($td, $x);

                        mcrypt_generic_deinit ($td);
                mcrypt_module_close ($td);

                return bin2hex($encrypted_data);
                }

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

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

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