Vincent Cheung came up with a clever way to encrypt a blog post that can only be decrypted by a Javascript key. This is a fantastic way to give your pals a wink and a nudge while keeping your blog accessible to all.

Writes Vincent Cheung:

The encrypted text is secure as long as you keep the key secret. The key is like a super-ultra secure password. You can use the same key over and over for multiple encryptions (so you don't have to remember/store multiple keys). If you want select people to see the encrypted text, you can give them the key. You may want to use a set of keys, one for super private, one for the gf, one for close friends, etc.

He also cautions that this should not be used for nefarious or illegal purposes. Honor system, guys. Honor system.
