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:

Homebrew Install Apache with PHP and MySQL on OSX

Setup a local Apache + PHP + MySQL + DnsMasq + PHPSwitcher environment using Homebrew on Mac OSX High Sierra that supports multiple versions of PHP and a self signed SSL certificate.

Install HomeBrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"	
brew doctor
brew update

ePorezi na macOS

Zvanična klijentska aplikacija Poreske uprave se može preuzeti sa njihove stranice.

U pitanju je Java aplikacija koja dolazi sa posebno priređenom distribucijom Oracle Java radnog okruženja. Aplikacija podržava samo Microsoft Windows operativni sistem i sertifikatima u Personals skladištu pristupa kroz Microsoft CryptoAPI koji poziva operacije na pametnoj kartici ili tokenu posredstvom midlvera.

Sertifikaciono telo Pošte korisnicima nudi SafeSign midlver, osim u verziji za Windows i u verziji za GNU/Linux i macOS operativne sisteme. Midlver isporučuje prateću aplikaciju za upravljanje karticom/tokenom i PKCS#11 biblioteku. Programi poput jSignPDF, Adobe Reader ili LibreOffice mogu da učitaju ovu biblioteku i omoguće korisniku elektronsko potpisivanje dokumenata.

Elektronsko potpisivanje se koristi i na portalu ePorezi Poreske uprave, posredstvom pomenute klijentske aplikacije.

Mac OSX Sierra : Brew Apache + Mysql + PHP Switcher + DNSMasq + SSL 👍

Things I had to do using Homebrew to get my local web dev environment back up and running after migration to OSX Sierra + Xcode 8.1.

Note: I used brew reinstall because I had already installed most of this previously under Yosemite. Probably better ways to do this, but this is what worked for me.

brew doctor

brew tap homebrew/dupes
brew tap homebrew/versions

PostgreSQL 9.x Sequence Fixing Script

This script is intended to automatically fix the sequence numbers for all tables in the current database.

This is accomplished through the use of the setval() command, which we provide with the next ID value we wish to make use of. We use the setval(sequence, number, is_called) overload and set is_called = false in conjunction with COALESCE(MAX + 1, 1) to ensure that, with an empty table, the next sequence value is 1 as expected.
