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.

Interactive Breadth First Search in a Grid
20 December 2020
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).

Lights Out Game
29 July 2020
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.
