Congratulations to Bill Briere for solving Challenge 17 in less than an hour after I posted it! He gets one point on the Leaderboard!
If you haven’t tried your hand at solving it, read this first.
Here’s original description and ciphertext:
It’s a relatively simple one. The title Aurous Coleoptera should be the only hint you need. To win, be the first to provide the solution AND the source of the quote.
“Aurous” is a synonym for gold. “Coleoptera” is the insect order of beetles. Combine them to get “The Gold Beetle” or “The Gold Bug.”
The plaintext is: “It may well be doubted whether human ingenuity can construct an enigma of the kind which human ingenuity may not, by proper application, resolve.”
This is a quote from the character Legrand in Edgar Allan Poe’s classic short story The Gold Bug. The cipher is, of course, “The Gold Bug cipher,” a simple substitution cipher that Poe created for his story. When The Gold Bug was originally published in 1843, it helped popularize cryptography and inspired many a young codebreaker.
The solid gold bug in the story was a scarab-like beetle.
You can make your own Gold Bug cipher by using Dcode’s excellent online tool.
With CodeAWeek.com, I hope to release one cipher, puzzle, or mystery each week. Anyone can attempt to solve. The winner is the first person to send a correct solution and a description of the solve method to email@example.com. Once a correct solution is e-mailed, I will publish a follow-up post, congratulating the winner and revealing the secrets of the code.
You may post questions or theories in the comments, but DO NOT POST SOLUTIONS. E-mail them to firstname.lastname@example.org.
