Download link to the plugin itself: CBhash.zip
Methods of encoding can be accessed through expressions or through actions.
Two actions are also available to configure the internals of the algorithms (unless you're experiencing trouble with the server-side, you shouldn't need to touch these).
The whole plugin is pretty documented within C2 (inline help).
And if you have trouble you can take a look at the Tech demo I put together and check its .capx
Oh yeah and CB Hash means CornedBeef Hash. (Thank you Lucid :D)
By the way, I did a tutorial related to the algorithms, hashes and how to use this plugin (as well as any custom plugin in general).
