Goal
data.txt contains text where letters have been rotated by 13 positions (ROT13).
Hints
- ROT13 is symmetric: applying it again “undoes” it.
tr(translate characters) is the simplest tool here.- Only letters are rotated; numbers/symbols stay the same.
Solution (click to reveal)
- SSH in:
ssh bandit12@bandit.labs.overthewire.org -p 2220
- Decode ROT13:
cat data.txt | tr 'A-Za-z' 'N-ZA-Mn-za-m'
That output is the password for Level 13.
Notes
- If you want to verify quickly: the decoded output should look like a normal password line.
