ROT13 focuses on alphabetic characters only, rotate alphabet 13 characters. After you run your string through the rot13 encryption you can create your own function to take care of the numbers.

There might be a better way but you can try this, it should only convert numbers.

function RotN5(strEncryptMe)
local stroutput = "";
for x = 1, String.Length(strEncryptMe) do
local num = String.Asc(String.Mid(strEncryptMe)
if num > 48 and num < 52 then
num = num+5;
elseif num > 53 and < 57 then
num = num-5;
stroutput = stroutput .. String.Char(num);
return stroutput;
