I want this encoder script to split up the characters so it's not one big long strand of code. It doesn't matter really how it splits it up.

I know there has to be a way to edit the code so it'll split it up and I've been trying to figure it out, but I just can't.

Your help is great appreciated.

Here's the script that needs edited:

<script language="JavaScript">

//Message Encrypter- By Naresh Hotchandani (nhotchandani@rediffmail.com)
//Script featured on Dynamic Drive
//Visit http://www.dynamicdrive.com for this script and more 

len=0;

function CalcKey()
{
len=0;
var temp=document.Encrypt.Key.value;

for(i=0;i<temp.length;i++)
{
len=len+temp.charCodeAt(i);
}
if(len==0)
{
alert('Please Enter the appropriate Key');
document.Encrypt.Key.focus();
}
return len;
}


function Encryption()
{

CalcKey();
document.Encrypt.Encrypted.value="";
var txt=document.Encrypt.normal.value;

var net="";
var fin=0;

if(len>0)
{

if(txt.length>0)
{
for(i=0;i<txt.length;i++)
{
fin=txt.charCodeAt(i)+len;

if(fin>99)
{
net=net+fin;
}
else
{
net=net+'0'+fin;
}
}

document.Encrypt.Encrypted.value=net;
document.Encrypt.normal.value="";
}
else
{
alert('Please Enter the Text to be Encrypted');
document.Encrypt.normal.focus();
}

}
}

function Decryption()
{
var txt=document.Encrypt.Encrypted.value;
var j=3;
var temp1;
var res="";

CalcKey();

if(len>0)
{
if(txt.length>0)
{
for(i=0;i<txt.length;i+=3)
{

var temp=txt.substring(i,j);
temp1=(parseInt(temp)-len);
var t=unescape('%'+temp1.toString(16));
if(t=='%d' || t=='%a')
{
res=res+' ';
}
else
{
res=res+t
} 
j+=3;
}
document.Encrypt.normal.value=res;
document.Encrypt.Encrypted.value="";
}
else
{
alert('Please Enter the Encrypted Text');
document.Encrypt.Encrypted.focus();
}
}
}

</script>

Thanks again,

use a loop and the string.slice method to split it up.

How do you apply that to the script so that it works?
