Bandit 10

Challenge

The password for the next level is stored in the file data.txt, which contains base64 encoded data

Commands you may need to solve this level

grep, sort, uniq, strings, base64, tr, tar, gzip, bzip2, xxdcccccbgkvtbhtkdchereljcbiegehfudtkihfcnnnrvl

Approaches

Base64 is an encoding. It’s not an encryption. Tools to encode & decode are readily available. Since I’m on *nix, i’ll be using base64. You can pipe strings into it to encode or decode them pretty easily, and it’s likely what i’ll be using.

Let’s see what we’re getting into.
