  • Pattern Words: A Solver's Staple

    While working on the Beginner’s Guide to the ACA, there was one technique that consistently showed up in all the research material: Pattern Words! At first I didn’t really understand how great they were. For those who don’t know about them or need a refresher, I’ll discuss a few of the different pattern types that I have come across. Afterwards, I’ll discuss my own Pattern Word Search Tool. Lets get started!

  • Beginner's Guide to the ACA

    When I first joined the ACA and opened my starter packet, I was eager to jump right in and start solving Aristocrats and Patristocrats. I tried to solve as many as I could. Once I got stuck I would try to learn a different way to solve in hopes that it would get me unstuck. There is so much great information available on solving different cipher types and trying out new techniques. Unfortunately, since there is so much great information, it is difficult to figure out where to start or what resources to use. I found myself frequently getting lost in material too advanced at the early stage and becoming quite frustrated when the information did not penetrate my thick skull.

    After one frustrating week, I contacted LIONEL, the ACA Recruitment Committee chairman, in hopes of finding some form of beginner’s guide to help me stay focused. He mentioned the “Young Tyros Newsletter”. It is a wonderful resource and I really recommend all new members and even non-members to read them. They have lots of great insights and tips to get you unstuck. In our discussions, I proposed that we should create a “Beginner’s Guide to the ACA”. I definitely didn’t want to re-hash all the great information out there. My goal was to compile a small list of the most important topics for a beginner to know and then point them in the right direction of all the other great materials out there.

    LIONEL put me in contact with a few members who graciously agreed to send me some of their notes on how they solved some of the lower level Aristocrat and Patristocrat cons. Their notes and insights have been a great help in increasing my knowledge and solving abilities. It took quite a long time and many iterations before I was satisfied with it but I finally finished the first version of the “Beginner’s Guide to the ACA!” This would not have been possible without the help of BECASSE, GGMA, LIONEL, MICROPOD, MATANZA, and ZANAC. I am very grateful for their help.

    You can download the Beginner’s Guide to the ACA below. Hopefully, it’ll help someone not get frustrated and lose interest in cryptology before they gave it a good chance.

  • Creating an interactive cryptogram solver (Part IV)

    Execute Interactive Solver

    I’ve been working hard on this part of the series because I really wanted the interactive cryptogram solver to make it quick and painless to jump right into solving and still give you plenty of room to expand the functionality and reflect your own style of solving. In this part of the series, we will create solver.py which will become our gateway to solving. It will allow us to quickly select a cipher class that we want to work with. We will also add a self documenting system that will allow us to use the solver without memorizing all the commands or shortcuts that each solver class may use. So, lets just jump right back into the code!

  • Creating an interactive cryptogram solver (Part III)

    Execute Interactive Solver

    In Part I and Part II of this series we created the framework for our interactive solver and finally had a working AristocratSolver class. In this part, we will enhance our existing framework by adding some commonly used functions, add frequency counting of characters and character sequences to the AristocratSolver class, add the ability to display the current plaintext and ciphertext keys to the AristocratSolver class and then finally create a PatristocratSolver class that reuses all our work in the AristocratSolver class.
