Richelieu

Rust-based implementation of the drunken bishop algorithm for fingerprint visualization

Getting started

The only required option is --data (or -d), containing data to encode. Run with the --help option to see other flags. An example run might look like this:

$ richelieu --data 'Hello, world!'
+-----------------+
|       oE ..     |
|    . oo*.o      |
|     o.= B       |
|     . .o X      |
|      . SB       |
|                 |
|                 |
|                 |
|                 |
+-----------------+

Note that the program does not currently include any hashing. Consider hashing data before feeding it to the drunken bishop.

TODO

• Ensure this works larger or more complex messages. Compare against https://www.jfurness.uk/the-drunken-bishop-algorithm/
• If we include hashing, we can print the hash algo at the top of the output frame.
• A fun variant might be a "wrap-around" board that avoids clipping to the edges.
