+**Bandit Wargames Writeup Code**
+
+Level 0:
+
+ssh command
+
+using code ssh <username@hostname> -- p 2220
+
+given password bandit0
+
+Level 0 -1:
+
+Using cat command we read the contents of the readme file to gte the
+required password.
+
+cat readme gives us the content of the readme file
+
+Level 1 - 2 :
+
+We need to find a file with name -
+
+We need to write command cat ./- in order to access the contents of the
+file as directly using -- would result in an error as -- has a specific
+function in linux shell.

+
+Level 2 -- 3:
+
+We need to access contents of a file named spaces in the filename
+
+We would use cat spaces\\ in\\ this\\ filename.
+
+MNk8KNH3Usiio41PRUEoDFPqfxLPlSmx
+
+Level 3 -- 4:
+
+We need to access content of a hidden file.
+
+We use command cd inhere to change directory from home to inhere.
+
+We then use ls -alps to list out all type of files.
+
+We then choose the hiding from you file and read the contents using cat.
+
+Level 4 -- 5:
+
+We need to find the only human readable file.
+
+For that, we need to access the type of file using find . -type f \|
+xargs file command.
+
+Xargs file→ passes those file paths to the *file* command, which detects
+and prints each file\'s type
+
+After ths we choose the file 007 as it is the only ASCII text type of
+file
+
+Then use cat filename to access the password.
+
+Level 5 -- 6:
+
+We need to use command find . -type f -size 1033c to get the file.
+
+-size 1033c for the size and type f for the humamn readable condition.
+
+Level 6 -- 7:
+
+We need to use command cd inhere to change directory and then use ind /
+-type f -user bandit7 -group bandit6 -size 33c 2\>/dev/null
+
+\- user for the user
+
+\- group for the group owner
+
+\- 2\>/dev/null: to remove all permission denied files.
+
+Level 7 -- 8:
+
+We need to find the password next to the word "millionth"
+
+So we use the command grep "millionth" data.txt
+
+grep command to find all the files which contain the word.
+
+Level 8 -- 9:
+
+The password is the line which occurs only once.
+
+We can use the sort filename.txt \| uniq -u command.
+
+If there are double lines, sort brings them together, while uniq -u
+prints the unique lines.
+
+Level 9 -- 10:
+
+Using strings command we access all the strings of the file and by using
+the grep "==" we find strings preceded by ==
+
+strings data.txt \| grep '=='
+
+Level 10 -- 11:
+
+We use the grep '=' command the get the most password looking like base
+64 encoded data. Then we use the base64 -d command to get the password.
+
+Strings data.txt \| grep '='
+
+echo "base64 encoded" base64 -d
+
+We're using echo to ****feed the Base64-encoded string into the base64
+command****.
+
+Level 11-- 12:
+
+We need to find the rotated alphabets.
+
+For that we use the tr command.
+
+tr \'A-Za-z\' \'N-ZA-Mn-za-m\' \< data.txt
+
+\'A-Za-z\' -- matches the upper case and lower case letters
+
+'N-ZA-Mn-za-m\' -- Rotates them by 13 positions
+
+tr translates the lines.
+
+Level 12-- 13:
+
+We use the following code for de-compressing the file:
+
+mv data.bin final.gz (if its a gunzip compressed file)
+
+We rename the file to final
+
+Then we decompress it using gunzip.
+
+Gunzip final.gz . Now we check for the file type, which if still needs
+to be compressed, will require from us to repeat the same steps.

+
+Level 13-- 14:
+
+This level does not require any password but wants us to use our private
+key instead of a password to login to level 14. For that, we need to
+check first if our ssh key is private using cat sshkey.private.
+
+Then we need to change the mode so that only **we **are able to read or
+write the file. Then we can use the private key to login.
+
+ssh -i sshkey.private bandit14@localhost -p 2220
+
+**-i sshkey.private**: tells SSH to use ****your private key**** instead
+of a password
+
+**bandit14@localhost**: log in as **bandit14** on the ****same
+machine****
+
+Level 14 -- 15:
+
+For this level we need to find a password to level 15-16 by giving a
+localhost or password of level 14.
+
+The password to level 14 could be accessed by cat
+/etc/bandit_pass/bandit14
+
+Then writing nc localhost 30000 would allow us to write our password.
