title: Not So Standard Substitution Cipher - DuckCTF 2023
date: 2023-08-04T00:00:00.000Z
description: I made a machine to implement a substitution cipher. The only issue is that it seemed to encrypt everything in sight, including my flag and all other random stuff. Each line in the attached file is a new piece of encoded information. Please save my flag! The flag will not be encased in `quack{...}`, but it will be the only reasonable text.

As we can see, the ISBN is partially corrupted, and the goal is to recover the ISBN and thus recover the book title.
