How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Tyranwyn

<VirtualHost *:8443>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

In the apps config/puma.rb file:

Change to match your CPU core count
# Check using this on the server => grep -c processor /proc/cpuinfo
workers 4

# Min and Max threads per worker
threads 1, 6

app_dir = File.expand_path('../..', FILE)

JWT Auth + Refresh Tokens in Rails

This is just some code I recently used in my development application in order to add token-based authentication for my api-only rails app. The api-client was to be consumed by a mobile application, so I needed an authentication solution that would keep the user logged in indefinetly and the only way to do this was either using refresh tokens or sliding sessions.

I also needed a way to both blacklist and whitelist tokens based on a unique identifier (jti)

Before trying it out DIY, I considered using:

arkadiyt

require 'base64'
require 'json'
require 'openssl'
require 'time'

def secure_compare(a, b)
  return false unless a.bytesize == b.bytesize

  l = a.unpack "C#{a.bytesize}"
