Hide your stuff under the mattress and you are vulnerable to a small population of burglars and the occasional catastrophe. Hide your files on the cloud and you become a target to the world! The advice is always – don’t leave important files in “plain” on public servers. The question is, how do you publish a file to a select few without having to trust server password security or complex programs. ZIP and PDF get close but it’s difficult to operate.
RedWrap is a novel approach. Take an HTML file, encrypt using BLOWFISH and publish as HTML that can only be viewed if you know the password. There are several advantages to browser based decryption.
- The password never gets as far as the public server
- The code can be audited by the great and good (it is there in plain JavaScript)
- Readers don’t need to install anything
- It defeats browser caching.
- You can add hints or preview information as you see fit
