Generating JSON Web Tokens (JWT) in Java or PHP

JSON Web Tokens (JWTs) are a mechanism for authentication that is simple to setup and easy to use. However, most of the time when you encounter this topic in a project, you get the advice to just use a JWT package. I am not quite sure why given that creating a token is relatively straight forward if you know how they are built. You can also implement such logic in ...

A Brief Overview of Honey Pot Form Fields

What is a honey pot field? Honey pot fields are HTML form fields that you put into your forms designed to catch bots (automated scripts that fill in forms attempting to spam). These fields are put in so that bots see them but humans do not. Perhaps the field is put into the form but hidden from normal users using a CSS style like "display: none;" or "visibility: hidden;". Since most ...

In this entry I am going to show you a bit of plain text file encryption using the Rijndael Algorithm. This example is a fairly simple one and I hope to explain the basics as I move through an ...

Rainbow Tables: Taste the Rainbow

But we don't have lions, ok, feed it to the bin of mutated rats growing a human ear!" The truth of the matter is that understanding the processes of password cracking can help protect and safeguard our electronic ...

Inside the World of Ciphers

Ciphers, a great marvel of mathematics and secrecy. They are the very heart of encryption, but how do we bring this to the world of programming and make some kick ass stuff with them? I had gotten the idea of showing some ciphers through a recent question that had been brought up. So I thought I would throw out some code from the dark corners of encryption for today's blog ...
