JS AES encryption example.

JS AES encryption example

This is a quick example of how to get symmetric encryption in JS using [aes.js from the crypto-js project][1]:

// at this point http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js should be loaded

var data = 'a JSON blob or something',
    password = 'my long and very secretive passphrase';

var encrypted = CryptoJS.AES.encrypt(data, password).toString();

Per-directory Bash history (w/o aliasing cd)

I use Bash’s PROMPT_COMMAND variable:

The value of the variable PROMPT_COMMAND is examined just before Bash prints each primary prompt. If PROMPT_COMMAND is set and has a non-null value, then the value is executed just as if it had been typed on the command line.

The source code should be pretty straight forward, but if not, please ask in the comments. Put this in your .bashrc or similar:
