irmago   GoDoc Go Report Card

irmago is an IRMA implementation in Go. It contains multiple libraries and applications:

  • The commandline tool irma, which contains an IRMA server; subcommands for manipulating IRMA schemes, generating IRMA issuer public/private keypairs, performing test IRMA sessions on the command line; and more.
  • The Go library irmaserver providing a HTTP server that handles IRMA session with the IRMA mobile app, and functions for starting and managing IRMA sessions.
  • The root package irma contains generic IRMA functionality used by all other components below, such as parsing IRMA schemes, parsing IRMA metadata attributes, and structs representing messages of the IRMA protocol.
  • The Go package irmaclient is a library that serves as the client in the IRMA protocol; it can receive and disclose IRMA attributes and store and read them from storage. It also implements the keyshare protocol and handles registering to keyshare servers. The IRMA mobile app uses irmaclient.

Documentation

Technical documentation of all components of irmago and more can be found at https://irma.app/docs.

Installing

git clone https://github.com/privacybydesign/irmago

irmago and its subpackages use Go modules for their dependencies. The go command will automatically download dependencies when needed.

To install the irma command line tool:

go install ./irma

Running the unit tests

Some of the unit tests connect to locally running external services, namely PostgreSQL and an SMTP server running at port 1025. These need to be up and running before these tests can be executed. They can be installed as follows.

PostgreSQL
  • Install using e.g. brew install postgresql, or apt-get install postgresql, or via another package manager of your OS.

  • Prepare the database and user:

    create database test;
    create user testuser with encrypted password 'testpassword';
    grant all privileges on database test to testuser;
    

    This only needs to be done once. No table or rows need to be created; the unit tests do this themselves.

SMTP server

For the SMTP server you can use MailHog (see also their installation instructions):

  • Install using brew install mailhog or go get github.com/mailhog/MailHog.
  • Run using MailHog, or ~/go/bin/MailHog, depending on your setup.

For the unit tests it only matters that the SMTP server itself is running and accepts emails, but MailHog additionally comes with a webinterface showing incoming emails. By default this runs at http://localhost:8025.

Running the tests

After installing PostgreSQL and MailHog, the tests can be run using:

go test -p 1 ./...
  • The option ./... makes sure all tests are run. You can also limit the number of tests by only running the tests from a single directory or even from a single file, for example only running all tests in the directory ./internal/sessiontest. When you only want to execute one single test, for example the TestDisclosureSession test, you can do this by adding the option -run TestDisclosureSession.
  • The option -p 1 is necessary to prevent parallel execution of tests. Most tests use file manipulation and therefore tests can interfere.
Running without PostgreSQL or MailHog

If installing PostgreSQL or MailHog is not an option for you, then you can exclude all tests that use those by additionally passing --tags=local_tests:

go test -p 1 --tags=local_tests ./...

Overview

Package irma contains generic IRMA strucs and logic of use to all IRMA participants. It parses irma_configuration folders to scheme managers, issuers, credential types and public keys; it contains various messages from the IRMA protocol; it parses IRMA metadata attributes; and it contains attribute and credential verification logic.
