Bill Cipher

thingiverse

Here's a simple bill cipher I came up with while experimenting with Tinkercad: I created this cipher as a fun project using Tinkercad, a free online 3D design tool. The idea behind it is straightforward: each letter of the alphabet corresponds to a specific number, and by replacing letters with numbers, you can create a coded message. To make things more interesting, I decided to use a rectangular prism as the base shape for my cipher. This allowed me to create a series of concentric squares that would serve as the grid for my code. The bill cipher itself is relatively simple: each letter of the alphabet is assigned a number from 1 to 26, with A corresponding to 1 and Z corresponding to 26. To encode a message, you simply replace each letter with its corresponding number. For example, if you want to encode the word "CAT," you would replace C with 3, A with 1, and T with 20. The encoded message would be "321." Using this cipher, I was able to create a small bill that reads: "HELLO WORLD." It's a simple code, but it's a good starting point for more complex ciphers. One thing to keep in mind is that the bill cipher can be easily broken if you know the frequency of letters in the alphabet. For example, E is the most common letter in English, so if you see a lot of 5s in your encoded message, it's likely that they correspond to Es. Overall, I'm happy with how my simple bill cipher turned out. It was a fun project to work on, and I learned a lot about Tinkercad and coding in the process.
