Docproof

Client library for Proof of Existence API.

Installation

Add this line to your application's Gemfile:

gem 'docproof'

And then execute:

$ bundle

Or install it yourself as:

$ gem install docproof

Configuration

Currently the only supported Bitcoin Payment Gateway is Coinbase, so if you want to use the Docproof::Document#notarize! you'll need to set the following environment variables:

COINBASE_API_KEY=YOUR-COINBASE-API-KEY
COINBASE_API_SECRET=YOUR-COINBASE-API-SECRET

and requires coinbase/wallet

require 'coinbase/wallet`

docproof_document = Docproof::Document.new('y0urd0cum3nt5ha256h45h')
docproof_document.register! && docproof_document.notarize!

You can also configure the Coinbase API Key and Secret like so:

require 'coinbase/wallet`

Docproof::PaymentProcessor::Coinbase.configure do |config|
  config.api_key    = 'YOUR-COINBASE-API-KEY'
  config.api_secret = 'YOUR-COINBASE-API-SECRET'
end

docproof_document = Docproof::Document.new('y0urd0cum3nt5ha256h45h')
docproof_document.register! && docproof_document.notarize!

Usage

To register a new document's SHA256 digest:

doc.register!

To post the document's SHA256 digest to the blockchain (making payment to indicated bitcoind address):

doc.notarize!

To lookup the status of the document's SHA256 digest:

doc.lookup!

Response

The JSON response is stored in Docproof::Document#response and keys with the value of empty string are ignored.

Errors

If the request is not successful, the gem will raise an error. All errors are subclasses of Docproof::Error.
