sign message to prove address ownership #50

Closed andrewchambers closed 10 years ago

(I also created a client issue for this)

Please add a feature to the server which allows a user to sign a message or string with the private key, and then allow another user to verify the signature proving the owner of an address authored the message.

I would suggest a stellard api call for sign_message(secretkey,message) -> signature and validate_message(address,sig,message) -> bool

Bitcoin clients have this, and its pretty important to be able to prove a gateway or address owner really did author a document.

This change is critical to support sending secure payment instructions to gateways. A stellar account can then sign a message with fiat account deposit instructions etc.

This would be done client side. There is an issue for it there.
