I started using steempeak about a week ago and I'm loving it! Great work people! Question: I'm toying with the idea of putting legal documents on the blockchain. Is it possible for me to encrypt a document using my public key so that only I could read it with my private key? The opposite would be nice too where I share a document in a post and an encrypted copy with my private key so that people with the public key could verify that the original has not been modified? OR providing signing on the document, especially now that the blockchain allows for changes after 7 days.

I want to write a Will and put it on the blockchain so that only my beneficiaries can see it. I know there are other uses as well. Any thoughts to how I could do this or if it would be a feature worth writing into the interface?
