• Interactive Encryption and Decryption using RSA 14 March 2022

  I had a bit of inspiration recently with Fermat’s Attack on RSA and decided to make an RSA demonstrator. It shows all the steps in performing an RSA encryption using 2 known primes. It might be useful during a CTF when trying to determine small RSA keys by hand. I’ll eventually post a follow up for implementing that attack for small p and q.

  Breadth first search(BFS) is a very powerful and useful algorithm for exploring graph like structures. A BFS searches it’s nearest neighbors first before moving on. It’s main use is to find a path using the fewest hops. Here we use it to explore a grid that can be modified by a user. In this grid, we have verticies (the grid boxes), and edges (the box north, south, east and west).

  Shown below is a lights out kind of game. Scores are not tracked or anything it’s just something meant for fun. The goal is to get the board either completely lit up or completely black. It inverts the color of whatever you click on and those directly adjacent squares. Those squares directly to the north, south, east and west.

• Pa Lottery Data Viz Tool 20 March 2019

  In this post, I provide access to a data visualizer for the Pennsylvania lottery using data I pull regularly from their RSS feed. This tool uses SQLite and some scripts to automatically pull data to this post which is then visualized using Chart.js. I created histograms of the most common drawn numbers for the drawings in which a particular number appears, and you can see that visualized below in the charts.

• Caeser Cipher Decoding Tool 12 May 2018

  A caeser cipher is a cipher that moves each letter by a fixed offset. You'll see these as a common challenge in easier CTF events. So, I wrote a tool to encode caeser ciphers and generic shift ciphers.

• Unicode Character Code Decoder 21 April 2018

  This application decodes a unicode string into it's character codes, and names. It's meant to come in handy with CTF events. You enter your string in the form below and it will print out a table with the decode of it. I created it because I found it really difficult to find a decent decoder that gave me the actual codes.
