[ale] HTML encryption?



In the second block of script, prepend Decode() with
document.writeln("<!--") and append write(ky) with document.write(" -->") .
Render in the browser, then view source. Or will the dynamically gen'd stuff
show up? Seems like I may have converted this to a quickie Java app.
