@exxellence/ws.js

WS.JS

A WS-* client stack for node.js. Written in pure javascript!

Currently supports:

* MTOM
* WS-Security (username tokens, x.509 digital signature)
* WS-Addressing (all versions)
* HTTP(S)

For more information visit my blog or my twitter.

Note:
An excellent package from Yaron.
I just tweaked it to suite our needs.

```

Notes:

By default incoming signatures are not validates. To validate these signatures when you create the security channel specify the validateResponseSignature parameter:

```javascript
var sec = new ws.Security({"validateResponseSignature": true} ...
```

Next specify the server certificate (the public key corresponding to the server private sgining key):

```javascript
sec.options.responseKeyInfoProvider = new FileKeyInfo("./examples/server_public.pem")
```

In the future the server certificate will be extracted from the BinarySecurityToken automatically (when available).
