description: "The TAs creating the endterm exam have suffered in the past from leaked drafts.
|
|
To protect themselves against further leaks they invented the *mega obfuscated secure advanced information communication* (mosaic) system.
|
|
The mosaic system encodes emails as QR-Codes and then applies the ultra secure protection algorithm.
|
|
We found a QR-Code that was not disposed properly in a waste bin.
|
|
Can you decipher the email?
|
|
Hint:
|
|
1. The mosaic algorithm adds decoy fake data to the QR-Code. It is mega secure after all!
|
|
2. Save yourself from the headache of searching for QR-Code libraries: https://github.com/NaturalHistoryMuseum/pyzbar"
