TransformJS is a jQuery plugin which exposes new CSS properties accessible through .css() and .animate() which you can use to apply and manage transformations to a jQuery element.

TransformJS uses feature detection to analyze the supported features of the browser it is running in and adapts accordingly and it maintains an in-memory matrix which it uses to apply the transforms.
The ability to use transforms without constructing huge stylesheets for x-browser compatability is nice.

Cryptico.js is an easy-to-use JavaScript library for encrypting text on the client-side.
It has support for RSA + AES methods and the text can be encrypted with any given bit length (228, 1024, etc.).

The content is encrypted with a public key and it can only be decrypted with that key (which makes sense if the recipient already has that information).
Cryptico.js doesn't require any JS frameworks to function and it is well-documented.
