Just took a closer look at the examples and played around with some code. It works really well and a surprisingly low footprint. Basically doing exactly what is promised.

However i wonder why there is no way (visible?) to generate words for Javascript? Or at least a documentation on how the format for those byte arrays is build.

Assuming this is a licensing thing, i would really suggest to not put limit in that way. On first impression i assumed that this is useable for free for everything except commerical projects.
