Goal: Find the password and log into level 12. The password is in data.txt file which contains rot13 encoded data.

First we will need to use cat to get the contents of the data.txt file.

bandit11@bandit:~$ cat data.txt 
Gur cnffjbeq vf 7k16JArUVv5LxVuJfsSVdbbtaHGlw9D4

Since we know that the text is rot 13 encoded. To derot13 decodercode this one we will use one of my favorite tools for working with different types of encryption and decryption called cyberchef. We will use the rot13 decoder.

Now we have our password for level 12 and we sign into the next level!
