• What a robust and easy way to encrypt a string with key without using Open SSL?

  - by Axel

  I don't want to use Open SSL or any very big none-built-in libraries for this. I only want to be able to encrypt a string with a key so you can't decrypt it without it. By the way, i already did a long search on stackoverflow and i've checked out those unsecure ways but i want something robust like md5 (which can be decrypted with a key). Thanks

• Support for encoding query string or POST data in YUI ?

  - by faB

  How do you encode a javascript object/hash (pairs of properties and values) into a URL-encoded query string with YUI (2.7.0 or 3.0.0 Beta) ? I want to do the equivalent of Object.toQueryString() from Prototype: I need this to encode parameters for GET and POST requests with YAHOO.util.Connect. It turns out YAHOO.util.Connect has a setForm() method to serialize a form but that still leaves me out cold to encode parameters for GET requests, or the 4th parameter of YAHOO.util.Connect.asyncRequest() to pass post data.
