Methods of Signing with GPG

Last updated March 28, 2021

There are now two ways to approach this:

1. Using gpg and generating keys
2. Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

# app/channels/hello_channel.rb
class HelloChannel < ActionCable::Channel::Base
  def say_hello(data)
    times_to_say_hello = data.fetch("times_to_say_hello")
    hello = "Hello, #{current_profile.name}!"

    times_to_say_hello.times do
      ActionCable.server.broadcast(current_profile.id, hello)
    end

require 'thread'

# Stupid simple "multi-threading" - it doesn't use mutex or queues but
# it does have access to local variables, which is convenient. This will
# break a data set into equal slices and process them, but it is not
# perfect in that it will not start the next set until the first is 
# completely processed -- so, if you have 1 slow item it loses benefit
# NOTE: this is not thread-safe!
