Hi,
If you are on CF 5 you can use a UDF I created called urlEncrypt. Here it
is. For directions go to http://loathe.mine.nu, or shoot me an email.

function urlEncrypt(queryString, key){
// encode the string

function urlDecrypt(key){
var queryString = cgi.path_info;
var scope = "url";

scope = arguments[2];

stuff = '<FONT color="red">not encrypted, or corrupted
url</FONT>';
} else {
// remove /index.htm
querystring = replace(queryString, right(queryString,10),'');
// remove the leading slash
querystring = replace(queryString, left(queryString,1),'');
// grab the old checksum
if (len(querystring) GT 2) {
oldcheck = right(querystring, 2);
querystring = rereplace(querystring, "(.*)..", "\1");
} else {
oldcheck = "";
}
// check the checksum
newcheck = left(hash(querystring & key),2);
if (newcheck NEQ oldcheck) {
return querystring;
}
//decrypt the passed value
queryString = cfusion_decrypt(queryString, key);
// set the variables
for(i = 0; i lt listLen(queryString, '&'); i = i + 1){
// Break up the list into seprate name=value
pairs
thisPair = listGetAt(queryString, i + 1, '&');
// Get the name
thisName = listGetAt(thisPair, 1, '=');
// Get the value

// Set the name with the scope
thisName = scope & '.' & thisName;

Hi,
Have u tried the DE function?
The help says
