A client library for interacting with ACA-py to build your own Hyperledger Aries controller in Golang

go-acapy-client

A library for interacting with ACA-py in Go.

Context

You can create your own Self-Sovereign Identity solution using the Hyperledger Ursa, Indy, Aries stack. Learn more about the background by watching these videos:

• The Story of Open SSI Standards
• Decentralized Identifiers (DIDs) - The Fundamental Building Block of Self Sovereign Identity

To become an Aries developer, attend these courses by the Linux Foundation on edx.org:

• Introduction to Hyperledger Sovereign Identity Blockchain Solutions: Indy, Aries & Ursa
• Becoming a Hyperledger Aries Developer

Installation

$ go get -u github.com/ldej/go-acapy-client

Compatibility

Both ACA-py and go-acapy-client are under active development and might be incompatible. Currently go-acapy-client supports v0.6.0-pre of ACA-py.

Development

Start a local Indy ledger network VON-network. Make a checkout of github.com/bcgov/von-network. Then run:

./manage start --logs

This starts 4 Indy nodes and a von-webserver. The von-webserver has a web interface at localhost:9000 which allows you to browse the transactions in the blockchain.

Start a Tails server for the revocation registry tails files: Make a checkout of github.com/bcgov/indy-tails-server. Then run:

./docker/manage start

Start an Aries-Cloud-Agent-Python (ACA-py) instance and configure the right command line parameters. Read about ACA-py and the command line parameters on my blog:

Examples

Create a client, register a DID in the ledger and create an invitation.

package main

import "github.com/ldej/go-acapy-client"

func main() {
    var ledgerURL = "http://localhost:9000"
    var acapyURL = "http://localhost:8000"
    client := acapy.NewClient(acapyURL)
    
    didResponse, err := acapy.RegisterDID(ledgerURL, "Alice", "000000000000000000000000MySeed01", acapy.Endorser)
    if err != nil {
    	// handle error
    }

    // Start aca-py with registered DID
    
    invitation, err := client.CreateInvitation("Bob", false, false, false)
    if err != nil {
        // handle error
    }
}

Webhooks

When an event occurs in ACA-py, for example a connection request has been received, a webhook is called on your controller on a certain topic. go-acapy-client provides a webhook handler where you can register your own functions to handle these events. Based on an event happening you can update your UI or inform the user about the event.

Read more about ACA-py webhooks on my blog.

func main() {
    r := mux.NewRouter()
	webhookHandler := acapy.CreateWebhooksHandler(acapy.WebhookHandlers{
		ConnectionsEventHandler:            ConnectionsEventHandler,
		BasicMessagesEventHandler:          BasicMessagesEventHandler,

	})
    
    r.HandleFunc("/webhooks/topic/{topic}/", webhookHandler).Methods(http.MethodPost)
    
    // and so on
}

func ConnectionsEventHandler(event acapy.ConnectionsEvent) {
    fmt.Printf("\n -> Connection %q (%s), update to state %q rfc23 state %q\n", event.Alias, event.ConnectionID, event.State, event.RFC23State)

    fmt.Printf("\n -> Out of Band Event: %q state %q\n", event.InvitationID, event.State)

You are free to choose the URL for your webhooks. Don't forget to set the command-line parameter for ACA-py: --webhook-url http://localhost:{port}/webhooks. The URL you provide to ACA-py is the base URL which will be extended with /topic/{topic} by default. So whatever URL you choose, make sure that:

• if the --webhook-url is http://myhost:{port}/webhooks
• then the webhooks handler should listen on http://myhost:{port}/webhooks/topic/{topic}

The acapy.WebhookHandler is web framework agnostic and reads the topic from the URL by itself. The handler returned by acapy.WebhookHandler has the standard handler signature func (w http.ResponseWriter, r *http.Request) {}.

TODO

• godoc
• Proper error handling
• Admin API Key
• Tracing via global config
• Automation of steps via global config
• Payment decorators https://github.com/hyperledger/aries-rfcs/tree/master/features/0075-payment-decorators
• Constructors for JSON-LD types
• Add types for roles, states, predicates
• Allow for a connection-less credential exchange
• Allow for a connection-less proof by making a QR code of a payload below. The base64 payload is the result of your call to /present-proof/create-request.
