The password for the next level is stored in the file data.txt in one of the few human-readable strings, beginning with several ‘=’ characters.
I use the file command once more to confirm the file is ascii text.
The strings command will spit out any lines which look to have readable text. I then filter the output through grep, looking for matches with the “====” string. The last line contains our password.
