The Encrypted Page Maker lets you paste in a HTML document, pick a password, and then hosts the resulting page at its own site. Simple public publishing, with the source code available in the page source.
The contents of you page is compressed using LZString.js and optionally encrypted using mjsCrypt.js, and stored in the hash of a loader URL. The page loader reads the contents of the URL hash and decrypts and expands the page, setting the value of body.outerHTML. Scripts will work as they are compiled and executed after the page is loaded. Cookies and localStorage will not work between pages as they are both wiped clean when the page loads.
The encryption is unproven, and may only act as a deterent. This page and the loading pages are served over HTTP without SSL so do not trust it with actual confidential infomation. This is a toy. I hope you can have fun with it. All source code is freely avaliable in the page source.
