Encryption at its best is nearly unbreakable. At its most fun, it’s flimsy and thousands of years old. Our latest challenge is to break an existing columnar transposition cipher, and the challenge details are located here as challenge 35, “Columns“, on our challenge hub.
Once you’ve gotten the spec, send us a function or script to find any codewords which could have been used to encrypt the input text on the link above. Email firstname.lastname@example.org with your answer.
You’ll need to log in with GitHub to see the challenge, and you can test your answer codeword on the challenge site as well.
