Document Registration on Waves blockchain

Using the old alpha wallet I added a “document registration” menu item.
It is possible to pick a file, calculate its SHA256 hash and store it on the blockchain to have a priority date for further legal use.
It is possible to use the program for trade marks, legal documents, mp3, avi and any type of file with a dimension less than 1Gb.
The project will be available on gitHub soon.
