A blog post I read today – can’t remember where now of course – mentioned a hunk of javascript that implements an encryption algorithm to keep a blog post encrypted unless the viewer types in a password. Not hugely practical, but interesting.
Google never forgets. It’s kind of scary to think that people can find all of the stupid things I said Way Back When, and will probably be able to find the stupid things I’m saying now for quite some time into the future.
So, I have a (partial) solution. Implement a {Wordpress|MT|Community Server|etc} plug-in that allows you to ROT13 posts (or parts thereof) and automatically un-rot13’s them when the browser loads them, using a little hunk of JavaScript. You could obviously vary the algorithm, but ROT13 is fast and easy, and none of the search engines are going to be randomly un-ROT13′ing webpages any time too soon.
In fact, you could use any reversible transformation to implement this – compression, base64, AES-256 (with the decryption key coded into the page), etc. There’s no security here – that’s not the point – but there is index-proofing.
I don’t actually have time to go learn how to build a WordPress plug-in, so I’m probably not going to actually do this. If you do and you manage to get rich doing it, I want a cut. ‘Nuff said.
