This is the unofficial OmniAuth strategy for authenticating via OAuth2 to ESIA (GosUslugi). Read more here

Built using omniauth-oauth2.

Add this line to your application's Gemfile:

gem 'omniauth-esia'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth-esia

OmniAuth::Strategies::Esia is simply a Rack middleware.

In Your Rails application:

# Gemfile
gem 'omniauth-esia'

# config/initializers/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :esia, ENV['ESIA_ID'],
    scope:    'fullname email',
    key_passphrase: 'password',
    key_path: "#{Rails.root}/config/keys/private.key",
    crt_path: "#{Rails.root}/config/keys/certificate.crt"
end

or in Your Rails application with Devise. See full instruction here

# config/initializers/devise.rb
Devise.setup do |config|
  config.omniauth :esia, ENV['ESIA_ID'],
    scope:    'fullname email',
    key_passphrase: 'password',
    key_path: "#{Rails.root}/config/keys/private.key",
    crt_path: "#{Rails.root}/config/keys/certificate.crt"
end

Read the ESIA docs for more details You can configure several options, which you pass in to the provider method via a Hash:

• client_id: ESIA identifier
• scope: a space-separated list of access permissions you want to request from the user. Example 'fullname gender email'
• key_path: path to private key. Default to config/keys/private.key
• crt_path: path to certificate. Default to config/keys/certificate.crt
• client_options: path to certificate. Default to https://esia.gosuslugi.ru. For ESIA's test environment set to https://esia-portal1.test.gosuslugi.ru

client_options: {
        site:          'https://esia-portal1.test.gosuslugi.ru',
        authorize_url: '/aas/oauth2/ac',
        token_url:     '/aas/oauth2/te'
      }
