OverTheWire: Bandit Level 11 to Level 12

Level goal: 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

As provided in the hint, we are required to perform a ROT13 “decode” on the file given. If you have been following this blog, you would have seen this InfoSec CTF which also requires to perform ROT13 decode to find the flag.

First, let’s look at the clue,

bandit11@melinda:~$ cat data.txt
Gur cnffjbeq vf 5Gr8L4qetPEsPk8htqjhRK8XSP6x2RHh

Now, we can decode this using the ROT13 tool.

The password to gain access to the next level is 5Te8Y4drgCRfCx8ugdwuEX8KFC6k2EUu.
