Better SSH Authorized Keys Management

A seemingly common problem that people encounter is how to handle all of your users authorized_keys file.

People struggle over management, ensuring that users only have specific keys in the authorized_keys file or even a method for expiring keys. A centralized key management system could help provide all of this functionality with a little scripting.

One piece of functionality overlooked in OpenSSH is the AuthorizedKeysCommand configuration keyword. This configuration allows you to specify a command that will run during login to retrieve a users public key file from a remote source and perform validation just as if the authorized_keys file was local.

Here is an example directory structure for a set of users with SSH public keys that can be shared out via a web server:

	# A simplified wrapper around the native 'url' module that returns "live"
	# objects: updates to properties are reflected in related properties. E.g.
	# updates to the `port` property will be reflected on the `host` property.
	#
	# The public API and behavior are pretty close to the native 'url' module's:

	class Booking < AR::Base
	# ...
	end

	# app/models/booking/create.rb

	class Booking::Create
	def initialize(attributes)

	# Call scopes directly from your URL params:
	#
	# @products = Product.filter(params.slice(:status, :location, :starts_with))
	module Filterable
	extend ActiveSupport::Concern

	module ClassMethods

	# Call the class methods with names based on the keys in <tt>filtering_params</tt>
	# with their associated values. For example, "{ status: 'delayed' }" would call
