Our task for bandit12 says:

The password for the next level is stored in the file data.txt, where all lowercase (a-z) and uppercase (A-Z) letters have been rotated by 13 positions

Well, let’s have a look at the data

cat data.txt

The string is shifted by 13 characters apparently. This is a well known substitution cipher called ROT13. You can use any decoder online, or even write one of your own!

For the purpose of this walkthrough, I am going to use the one at www.rot13.com

Just go there and use the decoder to decode the base64 string to a normal ASCII one.

Task completed!
