I wouldn't mind competing with Blocksign, or otherwise compelling them to apply their methodology to the Bitshares blockchain.

OK, excellent... Blocksign is the perfect demo for this tech.  Thank you deeply.

That sounds promising.  Does it exist?  This seems like a fairly straight forward request - like the first thing that blockchain would have been used for.  So an application should exist, true?

There are several of these cool services:

Does anyone know where I can find an off-the-shelf wallet application that can create a hash of a document and store it on the bitshares blockchain?...
and want to eventually develop a branded registry for securing engineering works.

Try out Alexandria (http://alexandria.media/#/media/type/book) and start getting familiar with IPFS (http://ipfs.io)...

The "False" flag in "sign_builder_transaction" needs to be set to True if you want to broadcast your transaction

Are you looking for a web app that private/securely stores PDF files but publishes their hashes publicly?

Thanks for the comments. Indeed we want to "do it". 

"Poor Man's Patent" is just a way to describe the functionality that we need in a simple way.  Actually, this application would reside behind the National Society of Professional Engineers membership curtain. Instead of "inventions", they would archive their "stamped" works upon an appropriate ontology on a secure server and the hash of those documents on a blockchain.  Those parts would come later, we just need to prove one step at a time.  No budget now, that's why I need off-the-shelf.  If demonstrable, they would fund, etc.   

Can anyone help mash something together?

do it

Great Idea.
I like it.

do it

Great idea. PM'ed you some thoughts.

Good idea - I think @roadscape has some experience in that direction?

I guess you could do something like that with Custom Operations.

What about two separate programs; 1. to create the hash and the other, a simple wallet, to load the key?  Does this make sense? 

Thanks
