**Level Information** > [!important] The password for the next level is stored in the file **data.txt**, which contains base64 encoded data.<br><br> > > **Commands you may need to solve this level:** > > - grep, sort, uniq, strings, base64, tr, tar, gzip, bzip2, xxd If we print the contents of `data.txt`, we can see that there is a single line of `base64` encoded data. Utilising the `base64` binary, we can use the `-d` switch to decode a given file. In this case we use this command to base64 decode the data.txt file to find our answer. **Full Command:** ```Bash base64 -d data.txt ``` ![[Level 10 - 11.png]]
