Plain Sight HTML/JS

I had written a text obfuscation tool in Java (https://github.com/jwhart175/plain_sight) a while back, and since I recently completed a javascript course, I thought I’d translate the whole thing into javascript.   The translated code and a simple form through which to use it can all be found in the .html file linked below.  This code and form can be embedded directly into websites as is or just opened in a browser.  The script does not require an internet connection to work, as it executes all functions locally without querying external databases and has no references to external classes.
