I was poking around on archive.org and notice 9 urls have been captured for the site. One of them is titled "http://findingassange.com/aes.js" which if you hover over the blue-circled date, gives you 4 separate captured pages and their timestamps.

This is what one of them looks like - https://web.archive.org/web/20161214025513/http://findingassange.com/aes.js

As I am not a programmer, I wondered if this is part of the encrypted data to be released or is standard for something else standard to websites.

An explanation would be appreciated.
