PHP converted to CF

I am trying to convert this php to coldfusion, but I am not sure what some of it is doing... like the ^ operator.  Any help would be super awesome

PHP:

<?php
$account_key = "whoisit28";
$api_key = "12345";

$salted = $api_key . $account_key;
$hash = hash('sha1',$salted,true);
$saltedHash = substr($hash,0,16);
$iv = "OpenSSL for Ruby";

$user_data = array(
  "guid" => "1234",
  "expires" => "2009-05-29 20:02:40",
  "display_name" => "Richard White",
  "email" => "rich@acme.com",
  "url" => "http://acme.com/users/1234",
  "avatar_url" => "http://acme.com/users/1234/avatar.png"
);

$data = json_encode($user_data);

// double XOR first block
for ($i = 0; $i < 16; $i++)
{
 $data[$i] = $data[$i] ^ $iv[$i];
}

$pad = 16 - (strlen($data) % 16);
$data = $data . str_repeat(chr($pad), $pad);
     
$cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128,'','cbc','');
mcrypt_generic_init($cipher, $saltedHash, $iv);
$encryptedData = mcrypt_generic($cipher,$data);
mcrypt_generic_deinit($cipher);

$encryptedData = urlencode(base64_encode($encryptedData));
?>

My CF so far:

<cfscript>
            account_key = "whoisit28";
            api_key = "12345";
           
            salted = api_key & account_key;
            hashed = toBase64(hash(salted,'SHA'));
            saltedHash = left(hashed,16);
            iv = "OpenSSL for Ruby";
            /*iv = arrayNew(1);
            for(i=1; i lte len(iv_list);i++){
                iv = mid(iv_list,i,1);
            }*/
           
            expires = dateadd("h",1,now());
            expires = dateformat(expires,"yyyy-mm-dd") &" "& timeformat(expires,"HH:mm:ss");
        </cfscript>

        <cfquery name="user" datasource="datasource">
            select contactid as guid, '#expires#' as expires, firstname + ' ' + lastname as display_name, email, 'http://www.mastercontrolcustomers.com' as url, '' as avatar_url
            from contacts
            where contactid = #contactid#
        </cfquery>
       
        <cfset data = serializeJSON(user)>
        <cfscript>
            for(i=1; i lte 16; i++){
                tmp1 = mid(iv,i,1);
                tmp2 = mid(data,i,1);
            }
        </cfscript>
