Breaking the Hutton 2 challenge

Authors: Thomas Kaeding


In 2018, Eric Bond Hutton posed a challenge online involving a classical cipher of his creation. It was broken nearly two years later by brute-forcing the keywords, and a new challenge that involves a modified cipher was posted. This is an explanation of how we broke the second challenge. We did so by scanning all books on Project Gutenberg for an acceptable match, then resolving any discrepancies and finding the keys.
