Error: Failed to execute JavaScript.

Please enable JavaScript for this app, then refresh this webpage.

Alternatively, if you do not want to enable JavaScript for this page (or maybe
you want to but cannot enable JS on a page-by-page basis) Click Here to save
this App as an HTML Application.

If the above link didn't open a "Save As" modal, you can manually do so using
the file menu:

- Click "File"
- Click "Save As"
- Navigate to where you want to save this App.
- Change the "Save as type" to "Web Page, HTML Only"
- Change the "File name" to "String Encrypter.hta"
  - The ".hta" at the end is the important part. 
- Click "Save"
- You can now double-click on the "String Encrypter.hta" file to use the App.
