Challenge: SPG (Crypto)

Description

After successfully joining the academy, you attempt to log in to eclass but your browser crashes and all your files get encrypted. The only artifact provided is a password generator script. Crack it to decrypt your files.

Solution

See solution.py for the full implementation. In summary:

  1. The generatePassword function can be reversed to recover the Master Key
  2. With the Master Key recovered, decrypting the cipher is straightforward
